Compact printed monopole antenna on liquid crystal polymer (LCP) for EWB applications

A compact tapered CPW-fed hollowed printed monopole antenna on the liquid crystal polymer (LCP) substrate with an extremely wide bandwidth (EWB) is introduced. The simulated results demonstrate that this antenna achieves an impedance bandwidth from 0.435 GHz to 14.52 GHz (33:1) for VSWRles2, and exhibits a nearly omnidirectional radiation pattern, while its area is only about 0.18 lambda
