Patent ID: 6999042

Claim:
An antenna system comprising: a monopole tower having a circumference; a plurality of first antennas each including at least one first radiating element operative for emitting a first radiation pattern; a plurality of second antennas each including at least one second radiating element operative for emitting a second radiation pattern, said plurality of first antennas and said plurality of second antennas arranged with a side-by-side relationship about said circumference of said monopole tower; a first feed network including a plurality of first phase shifters electrically coupled with said first radiating elements, said first feed network operative for varying a main beam direction of said first radiation pattern; and a second feed network including a plurality of second phase shifters electrically coupled with said second radiating elements, said second feed network operative for varying a main beam direction of said second radiation pattern independently of said main beam direction of said first radiation pattern.
