摘要

A free space combining and diversity antenna system for a fixed cellularstation transmits signals from more than one transmitter without using acombiner, such that the combination of the transmitted signals is done in freespace. Furthermore, multiple electrical antennas allow various receptiondiversity techniques to be employed. The station includes a plurality oftransmitters, each connected to a transmission antenna where the transmissionantenna may be a plurality of electrical antennas including a patch antenna,monopole antennas, dipole antennas, etc. The station further includes aplurality of receivers or transceiver-receivers connected to differentantennas, for employing reception diversity techniques. Isolators connectedbetween the antennas for each transmitter-transmitter, transmitter-receiver,transceiver-transceiver, transceiver-transmitter, and transceiver-receiverpair cancel transmitted signals received by the non-transmitting antennas.
