Abstract :
A planar inverted-F antenna type tunable antenna with U-shaped slot is proposed. A varactor diode is integrated between the slot and bias feeding strip line for tuning the operating frequency. This antenna covers from 1.64 GHz to 2.05 GHz refer to the dc bias voltage from 0 V to 20 V The frequency tuning range is about 410 MHz bandwidth which covers several mobile communication bands of DCS (1710~1880 MHz), PCS(1750~1870 MHz) and PCS(USA)(1850~1990 MHz). This antenna occupies a compact volume of 40 times 15 times 8 mm3. The simulation result is based on the Finite Integral Method.
