1) The document describes a coplanar waveguide (CPW) fed ultra-wideband (UWB) antenna with a band-notch feature to reject the WiMAX band (3.35-3.8 GHz). 2) The antenna consists of a circular disc truncated at the top with a folded U-slot etched near the edge to produce the band-rejection characteristics. 3) Measurements show the antenna operates from 3.1-12 GHz with rejection of the WiMAX band, and it maintains an omnidirectional radiation pattern and stable gain across the UWB band except at the rejected frequencies. - Download as a PDF or view online for free
