A planar circular disc monopole antenna with a broad bandwidth is presented, which is composed of a circular disc monopole patch and a rectangular ground plane, both printed on the two sides of a substrate respectively, and fed by a trapeziform microstrip feed line.The antenna has a wide bandwidth ranging from 1.89 to 19.26 GHz for return loss < −10 dB, and exhibits a nearly omnidirectional radiation pattern. In this article, details of the proposed antenna design approach and measured results are presented and discussed. © 2012 Wiley Periodicals, Inc.
