Influence of a Magneto- Dielectric Resonator on DVB-H Antenna Performances

International audienceA new antenna using a magneto-dielectric resonator is proposed for DVB-H application. Full band coverage between 470 MHz and 862 MHz is obtained using varactor diodes. Measured instantaneous -6 dB bandwidth is wider than 8 MHz all over the band. Design procedure and measurement are described. Measured return loss, gain, directivity and radiation pattern are presented for different frequencies. A gain of -9.2 dB is obtained at 470 MHz
