Abstract
A switched beam forming network is disclosed having an antenna array and an integral beam forming network configured to selectively provide directional and omnidirectional antenna radiation patterns. Four 90-degree hybrids are serially interconnected to form a 4×4 hybrid matrix. The hybrid matrix receives and transmits signals through antenna monopoles and is configured to selectively switch between directional and omnidirectional operation. At least four antenna terminals connect the hybrid matrix to the antenna monopoles. Four input/output ports connect the hybrid matrix to a transmit/receive network through connecting lines. A plurality of switches are selectively actuatable to form the beam forming network.
