Abstract

A compact dual band micro strip patch antenna is designed for C (4-8 GHz) band and X (8-12 GHz) band applications. The proposed antenna consists of a rectangular patch having four U-slots and one I-slot with H-shaped DGS (Defected Ground Structure). The antenna has overall size of 25 mm by 23 mm and gives bandwidth of about 140 MHz from 5.85 GHz to 6 GHz and of about 1.21 GHz from 7.87 to 9 GHz at resonating frequency of 5.9 GHz and 8.8 GHz respectively with DGS. The antenna without DGS mainly resonates at 6 GHz and 8.7 GHz. The antenna with DGS has return losses -16.29 dB at 5.9 GHz and -18.28 dB at 8.8 GHz, gain 1.2 dBi for 5.9 GHz and 4.4 dBi for 8.8 GHz. This antenna has been analyzed using IE3D electromagnetic solver.
