This paper presents a new dual-band, dual-polarized 1£4 antenna array design for telecommunication base station. One of the bands covers global system for mobile communication (GSM) band, while the other covers both digital communication system (DCS) and universal mobile telecommunication system (UMTS) bands. The antenna is based upon an aperture stacked patch layout and incorporates a simple and novel dual-layered feeding technique to achieve dual polarized radiation. For feeding the array elements, a corporate feed network is used. In order to achieve appropriate matching in both bands, a three-section Chebyshev transformer has been designed. The proposed antenna shows good port decoupling, less than i30dB for dual linear polarization over its operating bands. Peak antenna gains about 11dBi and 11.6dBi have been obtained for lower and upper bands, respectively. The efiort was directed toward the design of a single standalone dual-polarized antenna to cover all three bands.
