Abstract :
A coplanar waveguide (CPW) fed semi circular disc antenna with a modified ground plane is presented. The proposed antenna consists of a semicircular radiating patch and semicircular arc-shaped ground plane. To achieve extremely wideband, two modifications are introduced. The first one is to modify the ground plane, and the second one is to insert slits near the feed point. Theoretical results show that the proposed antenna operates over 3.0 to 40 GHz for VSWR <; 2. Details of the proposed antenna are presented, and simulated results show that the antenna has stable radiation patterns and good gain over its whole frequency band.
