A Varactor-Tuned DVB-H Antenna

This paper presents a novel technique for the design of a varactor-tuned antenna for DVB-H (digital video broadcast-handheld) application. This solution is based on loaded planar inverted-F antenna (PIFA) design. Resonance frequency of the antenna is electrically controlled and thus wideband operation is achieved. A tuning circuit consisting of a varactor diode realizes the needed antenna tuning impedances. Proposed method is verified creating a tunable antenna that covers (470 - 750) MHz and fulfills the specified gain requirement.
