Abstract

In this article a compact ultrawideband (UWB) circular patch antenna with a novel technique for rejecting the WLAN and WiMAX bands from the UWB frequency band is presented This method is based on applying a band notch structure instead of dual band notch system. The design of this UWB antenna is in the way that is able to reject the WiMAX band without using a filter structure and instead by introducing a semi C-shaped controllable notch band in the radiated patch which is capable of filtering the WLAN band The proposed antenna has compact size of 22mm x 30mm. The Measurement results are in relatively good agreement with the simulations. Copyright (C) 2009 Praise Worthy Prize S.r.l. - All rights reserved
