| Abstract: | This paper designs a dual-polarized antenna with low cross polarization and high isolation for WLAN.The antenna is composed of three function layers and two layers of dielectric substrates laminated at intervals.The function layers are a square radiation patch,a ground plane etched H-slot and two feeding networks with hairpin resonators.The second-order filter antenna is realized both the hairpin resonators and the radiation patch to broaden the band.H-shaped slot is etched on the ground plate to reduce the coupling current between the antenna ports and improve the isolation of the two antenna ports.The simulation results show that the impedance bandwidth is 2.4 GHz~2.5 GHz in port1 and 2.39 GHz~2.52 GHz in port2.It covers the band of WLAN(2.4 GHz~2.484 GHz).In the operating frequency band,the isolation between two ports is greater than 38 dB,and the cross polarization in E plane and H plane are lower than-28 dB. |
