Abstract
A novel wideband planar U-shaped antenna with meandering technique is proposed for TV White Space operation in 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 good pattern stability is obtained The antenna gain of 2.2 dBi up to 4.6 dBi is achieved for the operational frequency from 470 MHz to 798 MHz.
