ABSTRACT:
A microwave plane antenna including rows comprising pairs of parallel conductive line antenna elements configured as a pair of out-of-phase square waves and a signal feed circuit of strip lines arranged as a corporate feed network. The respective conducting paths which run from a main feed inlet end of the circuit to each signal receiving end of the respective elements being varied in length, so that the main beam direction can be set in a plane including that of the antenna and normal to lengthwise axis of the antenna elements for a remarkable increase in the reception gain.
