In this article, 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 a lumped capacitor (varactor) across the slot arms of the patch. By varying the capacitance values of loaded capacitor from 0.5 to 3 pF, the antenna is capable of achieving high tuning ranges from 1.70 to 2.15 GHz. The antenna performance is characterized in terms of the reflection coefficient, radiation pattern, and power gain. The predicted and measured results show fairly good agreement and confirm satisfactory impedance bandwidth characteristics and consistent radiation patterns over the tuned frequency range. © 2012 Wiley Periodicals, Inc.
