BROADBAND BUILT-IN ANTENNA WITH NEW ENCLOSED 3D COUPLING FEED STRUCTURE

Abstract

Wideband built-in antenna with an enclosed 3D coupling feed structure for wireless terminals is presented. With the proposed design scheme, a nine-band built-in antenna that covers GSM850/GSM900/GPSIDCS1800/PCS1900/WCDMA/Wi8ro2350/Bluetooth/WiMax 2500 is experimentally tested. This novel nine-hand built-in handset antenna is developed within the limits of a 40 x 17.5 x 6 mm(3) volume, achieving good agreement between measurement and simulation.
