A novel TRI‐band planar inverted‐F antenna for GSM/DCS/PCS operation in mobile handsets

In this article, a novel mobile handset planar inverted-F antenna (PIFA) for tri-band operation in GSM, DCS, and PCS bands is presented. This PIFA comprises a rectangular folded planar radiator, which has a J-shaped slot, suspended above a partially grounded substrate. In this antenna, two resonant modes are excited and originate a lower band for GSM and an upper band for DCS and PCS. The influence of several geometrical parameters of the antenna on its performance was investigated to achieve an optimal design. The fabricated prototype of the proposed PIFA has overall dimensions of 45 × 90 × 6.6 mm3. The measured 10 dB return loss bands of the antenna are 880–892 MHz and 1658–2079 MHz. © 2012 Wiley Periodicals, Inc.
