The main aim of this paper is to obtain a compact inverted U - slot on a patch antenna with a heterogeneous substrate for wireless application. The proposed inverted U – slot is integrated in the square shape patch antenna on a heterogeneous substrate for size reduction up to 47.4% with respect to conventional square shape patch antenna and to obtain enhanced bandwidth by multiband resonances frequencies from 1.33GHz to 8.2GHz. A proposed antenna is fabricated with a heterogeneous substrate and multiband nature of the compact inverted U - slot on a patch antenna with a heterogeneous substrate is studied using Ansoft HFSS 13.0 software. This procedure is approved tentatively and estimated results were in great concurrence with recreated results. The S11 parameters of U shape, Inverted U shape, C shape and inverted C shape is compared.
