Abstract

In this paper, a rigorous analysis of probe-fed WLAN disc antennas is presented. At low microwave frequencies, these types of antennas have a quite large physical size. Two different techniques have been proposed to reduce the size of the conventional antenna. The first by using of a central cylindrical post while the second by using a double stacked circular patch antenna. With varying of the post radius, the upper patch radius, and the dielectric constants a significant reduction is achieved by more than 50 % in some cases. The finite difference time domain (FDTD) with the perfect matched layer (PML) is used in the present analysis. The obtained results are compared with available published data and good agreements are found
