A Compact Band-selective Filter and Antenna for UWB Application

Abstract

A novel compact CPW ultra-wideband (UWB) antenna combined with a compact band-selective fllter is proposed. The proposed antenna without fllter satisfles the return loss requirement of less than i10dB over the frequency range of 3.0GHz to 12.1GHz. The optimized antenna has dimensions of 10£16mm 2 on a Te∞on substrate (r = 3:48) with good radiation characteristics and is easy to fabricate. The proposed antenna with fllter has the frequency band of 3GHz to 11GHz for VSWR less than 2.0 with a rejection band around 5.0 to 5.9GHz.
