The compact quad-band planar internal antenna for mobile handsets

This paper presents the design of a compact planar inverted-F antenna (PIFA) suitable for mobile handset applications. The prototype of the proposed antenna designs to satisfy specific bandwidth specifications of present-day mobile cellular communication systems, including the global system for mobile communication (GSM; 890-960 MHz), the digital communication system (DCS; 1710-1880 MHz), the personal communication system (PCS; 1850- 1990 MHz), and the universal mobile telecommunication system (UMTS; 1920- 2170 MHz). Therefore, it could be applicable for the existing and future mobile communication systems. Design details and experimental results are also presented and discussed.
