ABSTRACT:
An improved antenna system for use at high frequencies such as cellular communication and PCS frequencies, having a steerable, multi co-linear array antenna in which the number of radiating elements per co-linear array increases monotonically from the periphery of the antenna to the middle of the antenna, and wherein the antenna is connected to a Butler matrix feed network, thereby providing steerability of the radiation pattern associated with the antenna. The improved antenna system achieves significantly lower sidelobe generation as compared to antenna systems using multiple co-linear arrays of radiating elements in which the number of radiating elements per co-linear array is constant. The Butler matrix feed network is implemented via a microstrip fabricated printed circuit board without crossovers.
