Abstract :
An on-board printed WWAN/LTE antenna of simple structure disposed in a small clearance of 8 × 36 mm2 in the ground plane of shaped circuit board in a slim handset is presented. The shaped circuit board has a large rectangular notch such that the battery of the handset can be embedded therein to decrease the thickness of the handset, and lead to much enhanced bandwidth of the antenna disposed thereon. This is mainly because stronger surface currents on the ground plane of the shaped circuit board can be excited, which greatly helps improve the operating bandwidth of the antenna disposed thereon. The proposed design makes a simple, small-size printed PIFA capable of providing two wide operating bands to cover the GSM850/900 and GSM1800/1900/UMTS/LTE2300/2500 bands.
