Abstract
Conventionally, if several tasks have to be carried out simultaneously by receivers and transmitters, then a number of them are required, each having its own antenna. By employing the invention a single receiver or transmitter having one antenna can carry out a number of simultaneous tasks. A receiver has an array of antenna elements which receives signals and transmits them along conductors. Junctions include variable control means to apply a variable proportion of the signals on a conductor to one of a series of channels, each junction also giving a particular variable phase shift. By correctly selecting the amplitude and phase shift the outputs on the channels correspond to signals from respective directions of sensitivity of the receiver, and may be considered to represent a number of beams.
