In this paper, aperture coupled U-slot microstrip antenna with wideband stub is investigated. The dielectric constant of the substrate is 2.2 and the hight of the substrate is 62 mil. The impedance bandwidth (VSWR<1.5) of U-slot antenna with wideband stub is about 10 %. The bandwidth characteristic of U-slot antenna wish wideband stub is compared with that of antenna without it. And the results of parameter studies of the wideband stub provides the optimum characteristics of bandwidth and matching.
