ABSTRACT:
A power coupler including a differential phase shifter for differentially adjusting the relative phase between signals on a pair of signal lines; and a hybrid coupler which is coupled to the pair of signal lines. The power coupler may be employed in an antenna including first and second signal lines; a differential phase shifter for differentially adjusting the relative phase between signals on the first and second signal lines; a first set of one or more radiating elements; a second set of one or more radiating elements; and a hybrid coupler having a first port coupled to the first signal line, a second port coupled to the second signal line, a third port coupled to the first set of radiating elements, and a fourth port coupled to the second set of radiating elements. Elevation beam width is adjustable independently of azimuthal beam width.
