Abstract

Abstract: A novel arrow-shaped monopole antenna with a coplanar waveguide(CPW) feed line is presented. The element and the feed line are etched on the same side of a substrate. The antenna is analyzed numerically, fabricated and tested. The measured results are given, showing a 111.8％ bandwidth for the voltage standing wave ratio(VSWR) of 2：1 covering the 0.788～2.787GHz frequency range. The numerical results agree well with the experimental ones. The proposed antenna can be used conveniently in broadband communications.

Key words: monpole antenna, coplanar waveguide, broad bandwidth
