What is an antenna field?
Antenna field is a group of antennas, from which the signals are combined to form a single beam. It may include two or more antennas, while some fields can have up to thousands of individual components radiating signal. Antenna fields are used to improve the quality of the signal, minimize interference and focus the signal in a certain direction. They can also be used to detect where incoming signals come from. Also, an antenna called phase fields allows the rays from each antenna to cause interference that is used for control signals. One beam then moves in one direction, within the field of view up to 120 °. All antenna field functions are controlled by a computer and the position of the beam can be moved within a second. One of the most important advantages of the antenna fields is that the systems will work, even if one antenna fails. The quality of quality will be reduced, but the field will continue to work.
There are different types andNté fields. The linear field has one phase controller and antennas arranged in line. The beams can only be diverted in one horizontal or vertical plane, but the flat field can control the rays in two planes. This type is more complex and each antenna contains its own phase shift. The frequency scanning antenna field controls the beam according to the frequency of the signal; Back signals can be displayed in three dimensions.
Antenna fields can take different forms. It can be reached on the circuit board or its elements can be configured to the top of the mobile phone. The microstrip antenna field is very small and is often printed on mobile phones. Large antenna fields sometimes use military installations.
During the design phase, the antenna field is often a computer mode. Calculations for determining the size and capacity of the shaping of the beam each antenna in the field are complex. For this purpose is used computer software that can solve difficult mathematical problems and computers must have considerable strength for supportfor this ability. Some software programs can also visualize beam patterns under different conditions with a lot of detail. The function of the antenna field can therefore be determined before its position.
