CPW FED UWB Monopole With Double Band Notch Antenna With Compact Size

Abstract

In this paper the new antenna structures firstly a modified band-notched compact printed halfelliptical monopole antenna is proposed for ultra-wideband (UWB) applications. Wider impedance bandwidth can be achieved by carving two sectors on top-side of the semi-ellipse-shaped patch. Two connected arc-shaped slots with a variable angle between them are inserted in the patch to act as a filter structure. The proposed antenna is etched on a FR4 substrate with the size of 25 × 25 × 1.6 mm3 and optimized to operate over the frequency band between 2.5 and 15GHz for VSWR
