This article presents an antenna array with novelshaped defected ground structure (DGS) incorporated into the ground plane to enhance the bandwidth. It is observed that cross-polarization of the antenna is reduced by inserting omega-shaped DGS into the design. A 4 × 4 planar antenna with corporate feed has been designed with and without omega-shaped DGS into the ground plane. Four Omega-shaped DGSs have been placed vertically between the patch elements. These have been placed exactly at the back portion of the microstrip feed line in the ground plane. This antenna array is designed for dual-band applications. It has been observed that the bandwidth of the antenna get enhanced drastically. At 2.4 GHz, the bandwidth is 1860 MHz and at 5.8 GHz it is 2500 MHz with DGS. This type of antenna array can be used for WLAN and weather radar systems. The antenna has been designed using CST software.
