Abstract :
In this paper, a compact tuneable F-slot monopole antenna for mobile handset applications, covering the DCS, PCS, and UMTS frequency bands, is presented and studied. An F-shaped slot is embedded in a rectangular monopole patch to accommodate the varactor. The tuning is accomplished by applying DC voltage of varactor diode across the slot arms of the patch .By varying the DC voltage equivalent to capacitance values of loaded capacitor from 0.5 pF to 3 pF, the antenna is capable of achieving high tuning ranges from 1.70 GHz to 2.15 GHz.
