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.
