A wideband dual-polarized stacked patch antenna for base stations

This paper proposes a wideband dual-polarized slot-coupled stacked patch antenna operating at UMTS, WLAN (2.4 GHz) and UMTS II frequency bands. The antenna has been designed and optimized by using Ansoft Designertrade. A prototype has been realized and measurements were carried out showing good performance in the whole required bandwidth (33.4% bandwidth)
