Abstract—A novel printed monopole antenna with dual widebands p [C 9g  
is presented for simultaneously satisfying wireless local area *ai~!TR  
network (WLAN) and worldwide interoperability for microwave u @Ze@N%  
access (WiMAX) applications. The antenna structure consists of /(JG\Ut  
a rectangular monopole with a microstrip feedline for excitation 'Eur[~k  
and a trapezoid conductor-backed plane for band broadening. The %@vF%   
measured 10 dB bandwidth for return loss is from 2.01 to 4.27 2]mV9B   
GHz and 5.06 to 6.79 GHz, covering all the 2.4/5.2/5.8 GHz WLAN Sxq@W8W  
bands and 2.5/3.5/5.5 GHz WiMAX bands. IQO|)53)
