Abstract: A newly designed compact triband PIFA for mobile devices is presented. The antenna is printed on both faces of the printed circuit board (PCB) with             εr=2.8. The antenna size is reduced to 160 mm2 by folding, and 4 mm in width and 40 mm in length. The antenna is fed with a 50 Ω coaxial line. The obtained bandwidth covers three bands, centered at 900 MHz for GSM, 1 800 MHz for DCS, and 1 900 MHz for PCS, respectively. A prototype antenna is fabricated and measured. The measured results are consistent with simulated results.

Key words: GSM/DCS/PCS, miniaturized, planar invertedF antenna (PIFA), tri-band
