Abstract

In this article, we describe a novel type of defective ground surface (DGS) microstrip antenna which has higher gain, multi resonant frequency with compact size. It consists of hexagonal shaped patch with small volume and the ground plane is cut into six triangular slots just below the corners of the hexagonal patch. Antenna is circularly polarized one with gain 3.6dBi. The antenna shows multi resonant frequency. The proposed antenna is simple in structure compared with coplanar parasitic patch antennas. It is mostly suitable for wireless communications. slots is placed for improving the bandwidth.
