Abstract

A band-notched ultrawideband monopole antenna with a novel segmented radiating patch is presented. Band-notched characteristic in the 5.7-GHz WLAN band is obtained by segmenting a circular monopole patch into three parts. The measured results are in good agreement with the simulated ones. Moreover, the surface current and electric field distributions are analyzed and an equivalent parallel RLC circuit concept is applied to explain the band-notched function. On the basis of the equivalent parallel RLC circuit analysis, the notch frequency and bandwidth of the notched band can be widely adjusted by optimizing the key parameters.
