Abstract: This paper presents a compact zigzag inverted-F antenna with matching network for Wi-Fi operation in portable devices. The antenna occupies a very small area of 8 × 18 mm2 and provides high gain of 6.91 dBi with the peak return loss of -49.75 dB, VSWR of 1.006 and input impedance of 50.2045 Ω at 5.5 GHz. This antenna covers a 10 dB return loss bandwidth of 609 MHz (5250 MHz~5859 MHz). In addition an impedance matching pie filter is used to ensure impedance matching between the source and the antenna. As well, the antenna has acceptable radiation characteristics
