- In this article, we present a TRx stacked microstrip patch antenna with improved isolation using double spur-line band rejection filters (DSL-BRFs).The typical TRx stacked microstrip patch antenna designed to operate at Ku-band with downlink frequency band of 12.25-12.75 GHz and uplink frequency band of 14.0-14.5 GHz had inherent isolation of 16 dB within TRx-band. The isolation performance of the antenna was improved by at least 23.45 dB in Rx-band and 17.82 dB in Tx-band after introducing the DSL-BRFs into Tx- and Rx-feed networks, respectively. Because the DSL-BRFs are compatible to be embedded in 50-廓 transmission lines, the TRx antenna with the filters are remained in as same size as the antenna without filters. © 2013 Wiley Periodicals, Inc.
