Wideband dual-polarized patch antenna array on finite cylinder

A wideband dual-polarized patch antenna array on a finite conducting cylinder is investigated. By employing the L-probe coupling technique and phase cancellation technique together with two vertical sidewalls, a wideband dual-polarized array with high isolation (S/sub 12/ < -32 dB, 1.85-2.24 GHz) is fabricated and tested. The proposed antenna is suitable for various mobile communication applications, including smart antenna and MIMO designs.
