![]() In depth antenna theory can become quite complicated, but a qualitative and simplified theoretical explanation help help in understanding what is actually happening, how the radio antennas work, and how they can be optimised. ![]() An understanding of basic radio antenna theory will help the maximum be gained from any aerial system. As such, maximising the performance of the antenna is very important. If the radio antenna performance is poor, then it will limit the performance of the overall radio communications system, or whatever wireless system is using it. An antenna is required to radiate and receive the signals and therefore their performance is key to the operation of the overall radio system. Radio antennas are a key element of any radio communications broadcast or wireless system. Antenna Theory: aerial basics Radio antennas or aerials are essential to the operation of any radio system - understanding how they work and the basic theory is key to installing, optimising and designing antennas.īasic antenna theory Polarisation Resonance & bandwidth Gain & directivity Feed impedance
