A planar UWB antenna with tripple notched bands

This paper presents a rectangular planar monopole antenna with triple stop bands for ultra-wide band Applications. The antenna is compact size (24mm × 24mm × 1.6mm) and is covering the entire UWB band with VSWR < 2 except the band of WiMAX range from 3.07–4.73 GHz, the WLAN band range from 5.14–5.97 GHz and the ITU frequency band range from of 7.92–8.61 GHz. The three slots are added to this antenna to stop various bands. Different shaped slots i.e. inverted Z, C and U are introduced in radiating element to stop WiMAX, WLAN and ITU respectively. The antenna is simulated using High Frequency Structure Simulator (HFSS) using FR4 as a substrate.
