- Abstract
In this paper, a UWB antenna exhibiting frequency suppression characteristics for WiMAX and WLAN spectra is modeled and analyzed. The proposed geometry is composed of a circular radiating element. Impedance matching at higher frequencies is achieved by incorporating steps near the feedline. Introduction of arc-shaped slots in the radiator results in significant band rejection for 3.3-3.7 GHz, 5.15-5.25 GHz and 5.725-5.825 GHz. Designed antenna has an impedance bandwidth (VSWR < 2) of 9 GHz ranging 3-12 GHz. A prototype of the proposed model is fabricated on a low loss substrate. Comparative study of measured results to the simulated results depicts that the performance parameters of the antenna, e.g., impedance bandwidth, S-parameters and radiation characteristics meet the criteria for wideband applications.
