Abstract
An active circulator is integrated with a quarterwave short-circuited microstrip patch antenna to produce a fully duplexed transceiver with transmit and receive operation at the same frequency and with the same polarization, The active circulator antenna is shown to have 14-dBi t ransmit gain and 7.4 dBi receive gain with a transmit-receive isolatio n of 26.9 dB at 3.745 GHz, This active antenna has potential uses in b oth short-range communication and radar systems.
