Summary:
In this paper, we present a novel thin-film ultra-wideband (UWB) antennas with single or dual-band notched characteristics. A CPW-fed rectangular patch with a fork-like tuning stub radiates through a rectangular aperture, which ensures UWB impedance matching from 3.1 GHz to 10.6 GHz. In order to avoid interference with WiMAX applications at 3.3-3.7 GHz and WLAN applications at 5.1-5.8 GHz, the antenna is slightly modified to reject undesired band. A U-like slot ,and rectangular slot are etched on the ground plane at the notch frequencies. The designed antennas have a small size of 34.5×27.3 mm2 and thickness 0.3 mm. The VSWR, gain, and radiation patterns of the fabricated antennas are presented. A prototype was fabricated and measured, and the obtained experimental results agree with simulations.
