Summary:
This paper proposes a novel multi-band antenna design suitable for WLAN/WIAMX dualmode notebook application. The proposed antenna is printed on a 0.8 mm FR4 substrate, and consists of a T-shape monopole structure and a loop antenna with a L-shape shorting strip structure which is fed by coupling of the T-shape monopole. Through the adjustment of gap between the Tshape monopole and the shoring strip, a more uniform current distribution in shorting strip can be obtained and it can strongly reduce the antenna dimensions and enhance the antenna bandwidth. The proposed antenna has a compact size of 24 x 7.8 x 0.8 mm3 and a wide bandwidth in lower band and higher band defined by 2.5:1 VSWR, respectively, which can cover the WLAN 2.4 G band (2400 ~ 2500 MHz), WLAN 5 GHz band (5150 ~ 5850 MHz) and WIMAX bands (2300 ~ 2400 MHz and 2500 ~ 2700 MHz). Due to its compact size and planar structure, the proposed antenna is very suitable for the embedded antenna of notebook, especially in ultra-thin platform. Besides, the good antenna efficiency and radiation performance are obtained. Details of the proposed antenna and experimental results are presented and discussed.
