Özet

A broadband (1.71-2.17 GHz), high isolation, and dual-polarized suspended plate antenna (SPA) is presented. Modified L-probe feed is used for broadband matching and capacitive coupling. Port isolation between two orthogonally polarized channels is improved by making extensions on suspended plates (SPs) and inserting a vertical ungrounded square tube under the first SP (SP1). The prototyped SPA resulted in 8 +/- 0.5 dBi gain and 67 degrees +/- 66 degrees symmetric E-plane and H-plane radiation patterns with low cross-polarization levels. Return losses <=-15 dB and port isolation <=-30 dB are achieved in the entire band. (C) 2015 Wiley Periodicals, Inc.
