In this paper, the authors propose a novel T-shaped planar dual band antenna in that two inverted L-shapes are used as additional resonators to produce the lower and upper resonant modes with high return loss. As a result, a dual band antenna for covering 2.4GHz and 5.2GHz ISM/WLAN bands is implemented. The dimension of the antenna is 30x42x1.6 mm3 and provides an impedance bandwidth of 563.6MHz and 1743.6MHz at lower and upper frequency band respectively. The antenna system shows good radiation patterns as well as good total gains of 9.76dB and 4.28 dB. Detail design criteria with respect to geometrical parameter variation are given. The proposed antenna with relatively low profile is very suitable for multiband mobile communication systems.
