The numerical simulation of a low-profile dual band mirrored-F antenna for 3.5/5.5GHz WiMAX and 5.2GHz WLAN applications is proposed. It has a dimension of 29x14.5mm2 and the two resonant modes of the antenna provide bandwidth of 13.8% (3.35GHz-3.85GHz) and 17.4% (4.9GHz-5.85GHz) with maximum gain of 3.36 and 7.35dBi respectively. The peak values of return loss are -22.124 and -52.282dB and VSWR varies between 1.83-1.17 and 1.004-1.9 at the lower and upper resonant frequency bands. In addition, the antenna also provides almost omnidirectional radiation characteristics and excellent impedance matching.
