Dual band notched small monopole antenna with a novel T-shaped slot for UWB applications

A new type of ultra-wideband (UWB) antenna with a dual-notched frequency band, compact size of 12×15mm
²
and a coplanar waveguide (CPW) fed is proposed in this article. Two notched frequency bands are obtained by embedding two L-shaped slots in the radiation patch and a T-slot in the feed line and a V-shaped strip in the ground plane. Antenna has an impedance bandwidth ranging more than 140% from 2.75GHz to 18.46GHz in which voltage standing wave ratio is less than 2, expect two notch Frequency.
