Dual band-notched circular disc monopole UWB antenna with switchable five notched stop bands

Abstract

A dual band-notched UWB antenna with switchable five notched stop bands is presented. Predicated impedance bandwidth 3.2–15 GHz with dual notched stop bands 5.47–6.15 and 7.88–12 GHz are achieved by loading a modified T-shaped ring slot on the feed line with radiating patch. Furthermore, four diodes are employed on modified T-shaped ring slot on different locations to make antenna switchable at five notched bands. The radiation pattern and gain is analyzed and results presented.
