Antenna - How One Works

It's probably not something many habitancy are concerned in unless they're some kind of an electrical engineer or just bored, but comprehension how an antenna works can be useful when the one on your Tv or radio goes south on you and the imagine is beyond your comprehension.

Trying to elaborate how an antenna works in easy English is not an easy task as there are a lot of technical specifications that need to be explained. But a general comprehension is possible without getting into tech speak that would make Einstein cringe.

Antennae Or Antennas

In order for an antenna to work it has to radiate. Your antenna, either Tv or radio has what is called free electrons running straight through it. It is these free electrons that vibrate. The inquire becomes, how do these free electrons vibrate and what causes them to vibrate?

Well, in real life it takes an electric field to move an electron. If you take an isolated right dipole, the power comes from the combined fields of all the charged particles, both inevitable and negative, in the antenna. We'll call this field the antenna's coulomb field.

In increasing to this field, the antenna exhibits a magnetic field that is the sum of the magnetic fields of all the free moving electrons. The antenna also has a dynamic electric field that is the vector sum of the dynamic electric fields of all the free electrons. What we can do is detach the electric field of the antenna at any point in space into two components. One of the components will be in phase with the total magnetic field and the other will be 90 degrees out of phase. The in-phase component is the radiation field of the antenna and the out of phase component is the induction field. At the antenna, both fields are parallel to the metal surface.

What happens is that the coulomb field and the induction field fall off much more swiftly than the radiation field as the length increases from the antenna. When you reach distances greater than a few wavelengths from the antenna, you have what is called the antenna's far field. This field is pure radiation. As you get closer to the antenna you have what is called the antenna's near field. This field is a combination of radiation, coulomb, and induction fields. Still with us? Great, we're getting to the good part.

What ultimately happens with all these fields that makes it so that your Tv or radio picks up signals straight through your antenna is this. The free electrons moving straight through your antenna are moving at their maximum speed. The right hand half of your antenna accumulates electrons. The left hand half of your antenna is where the electrons depart and leave an excess of charged ions. The coulomb field produces an imbalance and opposes the electrons' rightward motion. The electrons then stop, coast for a bit and then head back towards the left. After they reach maximum speed they then stop and process is repeated, now heading back to the right. The effect is a vibration of free electrons that heats the metal and in turn generates electromagnetic waves.

And that, in as easy English as possible, is how your antenna works.

The Satellite Radio Antenna - choosing the Antenna That's Right for You

The Satellite radio antenna is one of three basic hardware components you'll need to receive those digital audio streams from your favourite Satellite radio service provider.

Although both providers offer similar services and use similar technologies, the associated hardware, along with the antenna, is designed to receive whether Xm or Sirius programming. We have read articles where listeners have interchanged antennas with some success but it is not recommended.

Antennae Or Antennas

The antenna's task is to pick up the signals transmitted from the Satellites and terrestrial repeaters scattered about the U.S., with a trustworthy receive performance. In order to accomplish this, the antenna must have an unobstructed view (line-of-sight) of at least one orbiting satellite. In urban areas where structure and terrain are likely to block the Satellite signal, the antenna picks up the signal broadcast from the terrestrial repeaters instead.

To ensure an uninterrupted Satellite radio service, both Sirius and Xm contribute recommendations for ideal antenna mounting locations. Furthermore, many home and plug-and-play Satellite radio units offer special antenna aiming screens within their menu options.

With a rapid advancement in Satellite radio antenna technology, Xm and Sirius are able to offer their listeners a wide range of antennas, accessories and flexible premise options.

So the question: Which Satellite radio antenna do I need? Although taste can play a small part in selecting the right antenna, the decision largely depends on whether you want to listen to Satellite radio in your vehicle, on your boat, at home or actually anywhere! One thing you can be sure of is that all Satellite radio antennas available today are neither too cumbersome, nor levy limitations on your vehicle, boat or home's aesthetics.

Antenna form Guide

This guide is intended to furnish a brief overview of the key considerations when selecting an antenna or looking to implement a convention antenna design. Unfortunately despite the great strengthen made on simplifying radio transmitter and receiver institute to the point where plainly following the guidelines laid down by the builder can follow in a working design, antenna institute still requires a grasp of the underlying theory.

Terminology

Antennae Or Antennas

Bandwidth: The range of frequencies on whether side of the centre frequency where the antenna characteristics (such as input impedance, polarization, gain and efficiency) are within an appropriate value of those at the centre frequency.

Directivity: The ratio of the radiation intensity in a given direction from the antenna to the radiation intensity averaged over all directions.

Efficiency: The estimate of power radiated, compared to the estimate of power at the input terminals of the antenna.

Gain: intimately related to directivity but takes into account the antenna efficiency.

Impedance: The impedance presented by an antenna at its input terminals.

Polarisation: The vector traced by the galvanic field as viewed along the direction of propagation.

Radiation Resistance: The equivalent resistance that would dissipate the estimate of power lost straight through radiation.

Theory

As mentioned in the introduction antennas can't be effectively designed and integrated without at least a basic grasp of the underlying principles. Unfortunately while there is some literature that manages to portray the law without resorting to involved mathematical derivations, most want a solid grasp of Vector Calculus to get much beyond the first chapter. In this report I will keep things as easy as possible.

It does not take long when researching antenna institute to realise that the illustrious Maxwell's equations underpin everything. Fortunately when expressed in "plain English" these are very easy to grasp and I suggest that anyone wishing to understand antenna institute should meditate on these equations until they can be expressed in your sleep!

Maxwell's equations are essentially a set of four equations from three of the times many scientists (Ampere, Faraday and Gauss). These are:

1. The galvanic flux straight through a concluded envelope equals the charge contained.
2. The magnetic flux straight through a concluded envelope is zero.
3. The galvanic field integrated colse to a concluded loop is equal to the negative of the rate of turn of the magnetic flux straight through the loop.
4. The magnetic field integrated colse to a concluded loop is equal to the total current that passes straight through it.

In overview one of the basic requirements for radiation is to maximise the magnetic field, and this is most effectively done by maximising the current and loop area.

There are three regions or zones when considering radiation from an antenna:

1. Reactive near field
2. The radiating near-field (Fresnel region)
3. The far field (Fraunhofer region)

The size of the reactive near field is given by R = 0.62*Sqrt(D3/W), where D is the largest size of the antenna, and W is the wavelength.

For electrically small antennas the Fresnel region does not exist. The Far-field can generally be assumed to start at 2*D2/W.

Antenna Types

Dipole

Possibly the most familiar antenna is the dipole, which plainly consists of a quarter-wave driven element and a quarter-wave element on the ground or return, this results in overall dimensions equivalent to a half wavelength. The dipole impedance is practically 73 ohms, and gain is practically 1.5dB

While providing a very easy and low cost antenna they are not very base for low power radio links due to the relatively large size.

Monopole

A monopole or quarter wave antenna is highly base in low power radio links and the institute is very simple. The impedance is practically 37 ohms and gain is practically 5dB. A monopole requires a large ground plane with dimensions of at least quarter of a wavelength, although it is quite appropriate to build your circuitry onto this ground plane. The radiating element should be at 90 degrees to the ground plane to maximize radiation.

A monopole can be "shortened" by inductively loading the antenna to sacrifice the over-all dimensions but the radiation efficiency will be reduced.

Printed Antennas (Pcb)

Pcb antennas come in many forms and in fact both dipoles and monopoles can be implemented as copper on the Pcb substrate to keep costs down and ease manufacturing. Some of the most base Pcb antennas though are both the patch antenna and inverted F (Pifa).

To institute an sufficient patch or Pifa requires both modeling software and a estimate of iterations, with the appropriate skills to optimize the design. The size of a rectangular patch is usually a quarter wavelength long and the width dictates the bandwidth. The impedance is a function of where the patch feed-point is located providing a degree of flexibility in matching to distinct chipsets. The dimensions of the patch can be reduced by loading the patch antenna; this is usually achieved using shorting posts to the ground plane at appropriate locations. The overall loop area should be maximized to ensure sufficient radiation.

A Pifa antenna is a extra case of patch antenna and gets its name from the appearance of the antenna as an "inverted F".

Antenna Measurements

Input impedance: The input impedance of the antenna is ideally measured using a Vector Network Analyzer (Vna), however an Swr meter or scalar analyzer can be used to test the return loss. The impedance is measured and specified at the centre frequency of the antenna.

Bandwidth: The bandwidth of the antenna is measured using a Vna or Swr meter and is typically specified for an Swr less than 2:1 or Return loss of whether -6dB or -10dB.

Pattern: The radiation pattern is best measured in an open field environment ensuring that the receiving or reference antenna is in the far-field. The antenna is then rotated straight through 360 degrees in both the horizontal and vertical planes to acquire polar plots of the radiation pattern.

Efficiency: In order to reckon the efficiency both the absolute gain and the directivity need to be measured.
