| Abstract | ||
| The goal of this paper is to enhance the bandwidth of a Rectangular Patch Microstrip Antenna, RPMA, operating at higher order mode, TM03 mode, using three techniques: thick substrate, capacitive-feeding and stacked patches techniques. The constant of substrate, for all designs, is 9.8 with loss tangent 0.001, Alumina substrate. Four RPMA’s operating at TM03 mode are designed: a conventional RPMA with two thicknesses, thin and thick substrate thickness, a capacitively-fed RPMA, and stacked capacitively-fed RPMA. The composite effect of integrating the three techniques is appeared in stacked capacitively-fed RPMA design. This design offer a wide bandwidth reach 65% with maximum gain 8.78dB. The performance of these designs(VSWR, the far field radiation pattern, and the current distribution) has been analyzed with the aid of Microwave Office software (MW-Office 2006,Version 7). | ||
