An Ultra-Wideband Antenna for Mobile Handset Applications

A printed open-ended slot antenna is designed for mobile phone application. The slot has a hybrid structure of a rectangle and a circle cut out of a 60mm×115mm ground plane, and fed by a microstrip line with a circular patch connected to a bent strip on the upper part of the patch. The proposed antenna provides a wide -6dB bandwidth covering 1.73-11GHz. It can be used in DCS1800, PCS1900, UMTS2000, TD-SCDMA, Bluetooth, LTE2.5GHz, WiMax, and UWB
