Résumé
A novel wideband planar U-shaped antenna with meandering technique is proposed for TV White Space operation at 470 -798 MHz band. The antenna consists of a U-shaped antenna backed by a partial ground plane. The meandering technique is applied by inserting several slots at the bottom part of the U-shaped for bandwidth enhancement. An impedance bandwidth of 95.2% is achieved when the planar U-shaped antenna is added with 21 slots. The radiation pattern confirms that a good pattern stability are obtained. The antenna gain of 2.2dBi up to 4.6 dBi is achieved for the operational frequency from 470 MHz to 798 MHz.
