A NOVEL QUAD-BAND (GSM850 TO IEEE 802.11A) PIFA FOR MOBILE HANDSET

In this paper, a novel planar inverted-F antenna (PIFA) with slotted ground structure is proposed for multiband mobile communication application. The multimode performance is applied for multiband operation in our design. The proposed antenna has good impedance matching characteristics for GSM850/900, DCS1800/1900, LTE2300/2500, IEEE 802.11a/b. The measured radiation efficiency of proposed antenna is all higher than 69% in GSM (824-960 MHz)/DCS (1710-1880 MHz)/PCS (1850-1990 MHz)/LTE (2300-2400 MHz, 2500-2690 MHz)/802.11b (2.4-2.48 GHz), and is up to 50% in IEEE 802.11a (5.15-5.825 GHz).
