A 2.3–14 GHz UWB planar octagonal antenna with modified ground plane

This article concerns the design of a new ultra-wideband antenna with an octagonal configuration and reduced size. The prototype has been simulated and designed as a monopole. It has shown a permissible agreement between simulations and measures and an operation of ultra-wideband from 2.3 to 14 GHz (143.55%) for wireless applications. © 2012 Wiley Periodicals, Inc.
