Asymmetric CPW-Fed UWB Antenna with Dual-Band Rejection Characteristics

Abstract

An asymmetric coplanar waveguide-fed (CPW) ultra-wideband (UWB) antenna based on L-strip technology with dual-band rejection characteristics is presented in this paper. The proposed antenna consists of a CPW-fed slot strip rectangular patch with L-strip open stub in the front side and two inverted L-shaped strips conductor with L-strip slot on the backed ground plane. The size of the proposed antenna is 25x25x1.6 mm 3, and the simulated and measured results show that the proposed antenna has good impedance matching and radiation patterns, and it operates in 2.93 GHz -12.94 GHz with dual-band rejection performance in the frequency bands of 7.61 GHz - 8.58 GHz and 9.13 GHz-10.03 GHz for satellite and X- band communication.
