Abstract

A compact ultra-wideband (UWB) antenna with dual band notch is proposed. The proposed dual band notched antenna is designed on FR4 substrate having e r = 4.4, tanδ = 0.0024 and height 1.6 mm. It works on frequency 3.1 GHz to 12 GHz and VSWR ≤ 2. Frequencies from 4.7 GHz to 6.8 GHz and from 8.3 GHz to 9.6 GHz are band notched. Radiation patterns with the frequency of 4.7 GHz, 6.8 GHz, 8.3 GHz and 9.6 GHz of proposed antenna are investigated in this paper. CST Microwave Studio has been used as simulation tool for design.
