This article presents a new miniature reconfigurable digital video broadcasting‐handheld (DVB‐H) antenna for a portable TV or tablet PC device. The antenna consists in a Printed‐Inverted‐F‐Antenna (PIFA) loaded by a varactor diode. The radiating element has a size of 30 × 30 × 5 mm 3 and is mounted on a 230 × 130 mm 2 ground plane. This antenna is able to maintain a return loss below −10 dB on a 8‐MHz bandwidth reconfigurable channel from 450 to 900 MHz. Then, this radiating element reaches to cover the whole frequency band specification of the DVB‐H standard while keeping a good efficiency despite of the strong miniaturization. © 2011 Wiley Periodicals, Inc.
