Abstract

A curvature CPW-fed ultra-wideband monopole antenna on LCP substrate is proposed. The proposed antenna has good performance over the entire UWB frequency range (3.1 - 10.6 GHz), which enhanced the impedance bandwidth by adding four notches on rectangular patch. It can be easily mounted in conformal shapes (e.g. cylindrical), because LCP substrate have many attractiveness, especially flexible characteristic, for use in many mm-wave areas. The radiation patterns for both structures have similar performance to the conventional monopole antenna, because the antenna is flexed along its radiating side. The simulated peak-gain variation is less than 5 dBi for both structure, which cover UWB frequency range
