Antenna field - a compactly located group of receiving and / or transmitting antenna-feeder devices created as a part of field or stationary radio nodes, radio stations, as well as on large modern watercraft and aircraft [1] [2] [3] .
Essence
If there are restrictions on the size of the antenna field , all of its elements, the number of which can be several tens, should be located relatively close to each other, but their electromagnetic interaction should be minimized, because it can significantly distort the shape of the radiation pattern , cause interference to radio signals, change a number of basic electrical parameters, etc. [1]
In order to reduce the mutual influence of different radio means, a variety of methods are used, for example [1] :
- connection of one antenna to several radio stations,
- the use of antenna systems with different polarization of the signal,
- spacing of radio carrier frequencies,
- variation in the spatial position of the antenna radiation pattern,
- and etc.
