Abstract

In this paper, a compact micro strip fed dome shape slot antenna for Ultra Wide Band (UWB) applications is proposed. The dome shape is obtained by rounding (blending) the corners of a hexagonal slot. To excite the slot, a micro strip feed and a rectangular shape tuning stub is used. One of the corners of the rectangular patch is chamfered while the others are blended for better impedance matching and return loss. The patch and the ground plane are printed on the opposite sides of an inexpensive FR4 substrate with overall dimensions of 24 mm × 35 mm. The experimental result shows that the proposed antenna has good impedance bandwidth of 10. 9 GHz from 2. 14 GHz to 13 GHz (143%) which covers the entire UWB Band. The stable radiation patterns which are nearly Omni directional in H-plane and dumbbell shape in E-plane have been achieved.
