Design and simulation of triple band GSM900/DCS1800/UMTS2100 MHz microstrip antenna for base station

In this paper, a simple dual-band dual-polarized aperture stacked patch antenna with double sided notch is presented. This antenna is suitable for operation in telecommunication base stations. One of the bands covers the GSM band, while the other covers both DCS and UMTS bands. The proposed antenna shows good port decoupling of less than -30dB for dual linear polarization over its operating bands. The antenna is based upon an aperture stacked patch layout and incorporates a simple dual-layered feeding technique to achieve dual polarization radiation. A peak antenna gain of about 11.8dBi and 7dBi has been obtained for lower & upper band respectively. The effort was directed towards the design of a single stand alone antenna; however, the performance would be better when it is incorporated as an array element.
