Abstract

A bidirectional high gain four-element printed dipole array for WLAN (2.4/5.8 GHz) applications is analyzed and successfully implemented in this paper. Each element used is a double-side printed dipole fed with a balance twin-lead transmission line. A wide-band balun is implemented for the dipole array. Both simulated and measured data are pretty matched. According to the measured results, the bandwidth with return loss less than -10 dB is about 280 MHz (2250-2530 MHz) and 510 MHz (5470-5980 MHz) in the two operating bands, the measured gain for 2.4 GHz band is between 4.5 and 5.9 dB, and 6.1-8.9 dB for 5.8 GHz respectively. Good shaped patterns have also been attained by tuning parameters of the dipole array.
