Abstract
This paper presents a broadband aperture fed stacked patch antenna. The notable features of this feed configuration are wider bandwidth and the shielding of the radiation patch from the feed structure. Aperture-coupled microstrip feed uses two substrates separated by a common ground plane. The slot can be of any shape and size and these parameters are used to improve the bandwidth. The radiation of the open end of the feed line does not interfere with the radiation pattern of the patch because of the shielding effect of the ground plane. This also improves the polarization purity. A very significant bandwidth enhancement achieved(73%) by adding a reflector at the bottom of the aperture coupled stacked microstrip antenna. and by optimizing the antenna’s dimensions, substrate materials and thickness, aperture dimensions and by positioning an aluminum foil at a particular angle as a reflector to stop the back radiation. The measured ultra bandwidth found to be 73% at VSWR = 2.0 at850 MHz. This antenna can find useful application in in-building mobile network coverage for CDMA and GSM frequencies.
