Abstract
In this paper, a GPS antenna is designed by using metal film which can be attached on the case of battery without additional space for antenna in GPS band operation. The proposed metal film has a half-wavelength slot radiator. The slot radiator is fed by th electromagnetic field coupled from the GSM850/PCS band antenna. The proposed GPS antenna obtains about 20 MHz bandwidth(VSWR<3) which can cover entire GPS band. The antenna has an average gain of -3.8 dBi.
