摘要：

In this study, a new compact dual-band antenna with overall size of 11 x 14.46 x 1.6 mm(3) has been designed, fabricated and tested. The proposed antenna consists of two inverted Omega-shaped strips loaded with two different comb structures. The fist comb of six elements connected to the first Omega-shaped radiating branch is used to decrease the second band lower cut-off frequency and cover the intended WLAN and WiMAX applications. In order to cover the 2.45 GHz WLAN band and further reduce the antenna dimensions, a second comb structure of 14 elements is attached to the upper radiating branch. The fabricated antenna covers the frequency bands from 2.42 to 2.6 GHz and from 4.25 to 6.77 GHz with a reflection coefficient of vertical bar S 11 vertical bar <= -10 dB. The antenna shows an omnidirectional radiation pattern in the H-plane and a monopole-like radiation pattern in the E-plane. The measured results agree well with the simulated ones which indicate that the proposed antenna is suitable to be used in the WLAN/WiMAX applications.
