Abstract

An internal shorted patch antenna integrated with a shielding metal case for UMTS mobile phone application has been constructed and tested, and good radiation characteristic has been also observed. The constructed prototype integrates the antenna and the shielding metal case, which provides a coupling-free space for the RF components, battery and other associated elements in the mobile phone. The integrated antenna shows no protruded portions and is very promising to be concealed within the casing of the mobile phone. Furthermore, the antenna occupies no space on the bottom ground or system ground plane. Experimental results have also indicated that the antenna shows acceptable impedance matching characteristic.
