UWB antenna with dual band notched characteristics having SRR on patch

Abstract

UWB microstrip rectangular patch antenna with dual band notched characteristics with SRR (Split Ring Resonator) slots has been designed on FR4 substrate and its analysis has been presented in this paper. FR-4 substrate has thickness of 1.6 mm, loss tangent of 0.02 and dielectric constant εr=4.4. Dual band-notched characteristics have been created in 4.8–5.4GHz and 8.9–9.9GHz using SRR-1 and SRR-2 slot on patch respectively. The proposed design has ultra wideband responses with dual band notched at 3.6–10.6GHz. Simulation work of proposed design has been done using CST Microwave Studio.
