Abstract:
A simple and novel printed monopole antenna with dual broad operating bands is presented. The antenna fed by a 50-Ω microstrip line is composed by dual twin-pair inverted-L shaped strips as well as a small back truncated ground. By properly selecting widths of these inverted-L shaped stripes, dual broad bandwidths formed from triple resonances to meet the band requirement of the 2.4/5.2/5.8 WLAN or the 2.5(3.5)/5.5 GHz WiMAX standard can be achieved. Experimental results for case of the obtained antenna prototype suitable for use in a 2.4/5.2/5.8 GHz WLAN system have been done and shown good agreement with simulation. Good radiation performances including dual wide bandwidths of 270 MHz and 3.16 GHz, high average antenna gains of ≥ 2.6 and 4.6 dBi, and monopole-like radiation patterns over the two operating bands, respectively, make this antenna a good candidate for use in the modern dual-broadband wireless communication system.
