Dual Wideband Printed Monopole Antenna With Periodic Ebg Structure For Wlan/Wimax Applications

A novel printed monopole antenna with dual wideband is presented for simultaneously satisfying wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The antenna structure consists of a rectangular monopole with a microstrip feed line for excitation and a trapezoid conductor-backed plane for band broadening. The measured 10 dB bandwidth for return loss is from 1.9 to 4.32 GHz and 5.1 to 7.18 GHz, covering all the 2.4/5.2/6.0 GHz WLAN bands and 2.5/4.0/6.2 GHz WiMAX bands.
