Abstract

A printed CPW-fed monopole antenna with dual band-notched characteristics for UWB applications is presented in this paper. By
etching both inverted elliptical split ring slots on the radiating patch dual band-notched characteristics are obtained a narrow bandwidth at 3.3-3.8 GHz for WiMAX (3.3-3.7 GHz) and for WLAN (5.725-5.825 GHz) operating bands are achieved. The physical structure of the proposed antenna is printed on the 28 mm × 34 mm × 1.6 mm size FR-4 dielectric substrate. The presented antenna has a wide impedance bandwidth of 2.89 to more than 14 GHz expect of two notch bands. The antenna operates for the entire UWB (3.1-10.6 GHz) range and gives omnidirectional radiation patterns and stable peak gain expect at the band-notched frequencies. The proposed antenna has a planar geometry which is a good choice for any portable UWB communication system applications.
