A novel dual-band design of patch antenna is presented in this paper. Using a T-shaped parasitic strip, the patch antenna is able to generate two separate resonant modes to cover 2.4/5.8 GHz (wireless local area network) WLAN bands with satisfactory radiation properties. The impedance bandwidth of the proposed antenna is 250MHz centered at 2.42 GHz and 750MHz centered at 5.78 GHz for S11 < −10dB. The parameters which affect the performance of the antenna in terms of its frequency domain characteristics are investigated.
