Wideband tunable PIFA antenna with loaded slot structure for mobile handset and LTE applications

  A compact planar inverted F antenna (PIFA) with a tunable frequency response is presented. Tuning of the resonant frequency is realized by loading a varactor on an embedded slot of the proposed antenna structure without further optimizing other antenna geometry parameters. The antenna exhibits a wide frequency range from 1570 to 2600 MHz with a good impedance matching (S11 ≤-10dB) covering the GPS, PCS, DCS, UMTS, WLAN and LTE systems. To validate the theoretical model and design concept , the antenna prototype was fabricated and measured. The compact size of the antenna is 15 mm × 8 mm × 3 mm, which makes this antenna a good candidate for mobile handset and wireless communication applications.
