Abstract
In this letter, a printed planar inverted-F antenna is proposed for a quad-band operation.The proposed quasi-rectangular loop configuration yields the first and second resonant frequencies at 900 and 1800 MHz, respectively. The additional shorted strip on the bottom can expand the bandwidth at the upper band. The proposed antenna area is 8 × 38 mm 2 and the ground size is 72 × 40 mm 2. The measured impedance bandwidth, determined by 3:1 VSWR, has fully covered the GSM900 (880-960 MHz), DCS (1710-1880 MHz), PCS (1850-1990 MHz), and UMTS (1920-2170 MHz) frequency bands. The measured gain is higher than -1 dBi over the entire quad-band.
