UWB antenna with superior low‐frequency performance

This article presents the design of a compact, low-profile planar antenna with a circular radiator. With careful design of the radiator and ground plane, the antenna's low-frequency range extends to 1.5 GHz, in addition to operating as an ultrawideband (UWB) antenna across the entire Federal Communications Commission allocated UWB range. © 2016 Wiley Periodicals, Inc.
