Abstract

A compact dual-band Planar Inverted-F Antenna (PIFA) working in both the DVB-T (Digital Video Broadcasting-Terrestrial) and the WLAN (Wireless Local Area Network) IEEE 802.11b,g frequency bands is presented. It is designed to be integrated in a monitor-equipped device, and exhibits reduced electrical size with respect to similar PIFA configurations. A reflection coefficient less than 6 dB and 10 dB was obtained in the 470–862 MHz (59% percentage bandwidth) DVB-T and the 2400–2484 MHz (2.7% percentage bandwidth) WLAN bands, respectively. An antenna gain of almost 3 dBi and 4.5 dBi, with more than 95% radiation efficiency, was obtained in the two frequency bands of interest. The PIFA fills an overall volume of and can be realized by a properly cut and fold single metal sheet. Measurements on prototypes have shown that the proposed layout is robust in terms of the impedance matching detuning that can be caused by the presence of metal parts nearby the antenna.
