Abstract
In this paper, the antenna which has a multiband operation (GSM850, EGSM, DCS1800, USPCS, W-CDMA) is proposed. This antenna was designed by the commercial software HFSS 3-D EM simulator, and it is organized by using a meander branch structure which has a via and lines on FR-4$(\varepsilon_r=4.4)$ substrate. Especially, it has a gap feeding structure which makes good operation at overall bandwidth. The designed antenna is manufactured by PCB processing, and measured by using a network analyzer and a test chamber. The manufactured antenna with the dimension of 8 mm width, 20 mm height and 3.2 mm thickness is able to applied as an internal antenna for multiband mobile phones.
