An extremely wideband/multiresonance monopole antenna with multiple notched stop bands

Abstract

A wideband/multiresonance monopole antenna with multiple notched stop bands is presented. A multiresonance characteristic 2.6–22 GHz is achieved by modifying ground plane and three notched stop bands at 3.36–4.11, 5.15–5.79, and 7.96–8.50 GHz are achieved by introducing three co-directional split ring resonators (SRRs) in the radiating patch. The individual notch frequency is controlled by the individual SRR and central notch frequency is calculated by the physical dimension of individual SRR.
