Abstract

In this paper, we propose the antenna which has a wideband operation (GSM850, EGSM, DCS1800, USPCS, WCDMA). This antenna is designed by using a meander branch structure which has via and lines on FR-4(epsiv_r=4.4) PCB. The antenna was designed by the commercial software HFSS 3-D EM simulator. The designed antennas are manufactured by PCB processing, and measured by using the network analyzer and test chamber. The antennas with the dimension of 8 mm width, 20 mm height and 3.2 mm thickness, are applied on the internal antenna for wideband cell phones. Its size was minimized so that it can be mounted inside of a cellphone.
