Dual-band bidirectional high gain antenna for WLAN 2.4/5.8 GHz applications

A dual-band bidirectional high gain dipole array antenna for WLAN (2.4/5.8 GHz) applications is proposed and analysed. The array antenna is composed of four elements. Each element is a double-sided printed dipole which is fed with a balanced twin transmission line. Measured results agree very well with simulation results. According to the measured results, the bandwidth with a VSWR less than two is about 400 and 1100 MHz in the two bands,...
