Multi-transceiver antenna

摘要

The inventive antenna coupling system is capable of simultaneously radiating an omnidirectional signal pattern for a plurality of transmitters as well as providing a directive pattern to a receiver. An antenna array is coupled to the transmitters and receiver via a plurality of antenna couplers. Each coupler includes an antenna terminal, coupled to a corresponding antenna, a transmitter input terminal and a receiver output terminal. Multiple transmitters are coupled to the transmitter input terminals through a hybrid network array. The receiver is coupled to the receiver output terminal via a logic controlled antenna switch. The antenna couplers, which may be comprised of either high pass-low pass filters or circulators provide isolation between the transmit and receiver signals.
