Abstract:
In this paper, we propose a new design for a frequency notched ultra-wideband (UWB )antenna with a coplanar waveguide (CPW) bandstop filter using a slot-type split-ring resonator (STSRR). To notch the wireless local are a network(WLAN)frequency band, a STSRR resonant at the unwanted frequency is inserted into the centerline of the CP Wofthe UW Bantenna.The characteristics of the antennas such as returnloss, VSWR, surface current, group delay and gain are measured to prove the notched function of the proposed antenna. Also, the radiation pattern of the antenna is monopole like.The measured results show that the proposed UWB antenna is a good candidate for UWB applications. 2008 ElsevierGmbH. Allrightsreserved.
