This paper presents results for a novel active transmit‐receive antenna and designing a high port isolation dual frequency orthogonally polarized inset rectangular patch antenna. Measurements show an improvement of 20 dB in port isolation relative to the conventional antenna, operating at 2.4 and 2.6 GHz. An inset microstrip patch antenna operating at 10.5 GHz having 12.22% bandwidth has been used as a reference antenna. It is also shown that the return loss level of the antenna has been enhanced by using active matching with RC mutator networks from −10.62 dB to −14.76 dB respectively. In addition, this paper presents the design of an integrated 2.4/2.6 GHz full duplex dual‐band antenna transceiver for WLAN 802.11 a/b/g applications. © 2007 Wiley Periodicals, Inc.
