The compact multi-band internal chip antenna

This paper suggests a miniature internal chip antenna with quad band for operating at multi-band handset applications, including global system for mobile communication (GSM), digital communication system (DCS), personal communication system (PCS), and universal mobile telecommunication system (UMTS) band. The proposed antenna can be easily placed in practical handsets because of the small size of 28.3 times 5.1 times 3.2 mm³ . The electrical and structural characteristics of the proposed antenna make it attractive for use in mobile handset applications.
