Dual-port LCP multi-band antenna for Wibro/mWiMax MIMO, Bluetooth and GPS applications in mobile phone

The proposed LCP MMMB Wibro MIMO antenna has a good bandwidth (VSWR 3:1) performance at the band of Wibro1/Bluetooth and GPS/Wibro2. It is also got the average radiation efficiency more than 30% except Wibro1. However, it could be improved by a little antenna matching tuning on the mobile handset. This antenna can be also used switchable because of two signal lines.
