In this paper, we present a frequency reconfigurable antenna for digital video broadcasting on handheld devices standard. By loading a printed inverted F antennas with a varactor diode, the resonance frequency can be tuned from 470 to 862 MHz. Furthermore, a magneto dielectric superstrate is used to reduce the dimension of the antenna while keeping a large bandwidth. To study the performance improvement due to the magneto‐dielectric resonator,a comparison is performed with a reference antenna without magneto‐dielectric superstrate. © 2013 Wiley Periodicals, Inc.
