Summary:This paper suggests a miniature wideband internal antenna with dual resonant structures for operating at multi-band handset applications. It consists of two radiation monopole elements with parallel connection in the limited handset interior space. The proposed antenna can be easily placed in practical handsets because of the small size of 20 /spl times/ 17 /spl times/ 3.5 mm/sup 3/. The measured bandwidth of the proposed antenna shows about 1 GHz from 1.71 GHz (DCS band) to 2.71 GHz (Bluetooth band) with VSWR below 2. It also resonates at GPS band of 1.57542 GHz. The electrical and structural characteristics of the proposed antenna make it attractive for use in mobile handset applications.
