Abstract

Defected Ground Structure (DGS) technique has been largely investigated in recent years, particularly in the development of planar antennas [1]-[5]. The technique has been proven to improve some characteristics of the antenna for certain applications such as reduce mutual coupling in a microstrip array, and reduce cross polarization radiation on a single element. The approach employs simple and easy designs to be etched on the ground plane, that disturbs the current distribution but improve the performance of the antenna. The work of [2] has been further investigated with two different sets of DGS slots. This paper presents the design of two sets of microstrip circular patch (MCP) antennas with variations of horizontal and vertical DGS slot elements. Each set began with a pair of short rectangular slots, and proceeded to increasing the slot sizes to form long rectangular slots, and finally U- and T-shaped DGS slots. The antennas were named MCP_DH and MCP_DV antenna sets. The effects of introducing DGS pair of slots into the MCP ground plane have been successfully investigated [6].
