Abstract
In this paper, dual-polarized 2${\times}$2 array antenna is designed and fabricated for the polarization diversity applications in wireless LAN system. For the improved bandwidth and isolation characteristics, the aperture coupled feeding and the L-shaped probe feeding are employed for each polarization. The measured bandwidths of the fabricated antenna are 210MHz for aperture coupled feeding and 280MHz for L-shaped probe feeding. The isolation for two ports is -40dB and the antenna gain is measured as 14.3${\pm}$0.2dBi in the operating frequency band of wireless LAN.
