Design of Dual-Polarized Beamforming WiFi Antenna Array for FTTR Applications

Fiber-to-the-room (FTTR) for the fifth-generation fixed network (F5G) systems requires wireless capability comparable to gigabit optical network. This paper presents a dual linear polarization, low profile and low cost magnetoelectric dipole (ME-dipole) antenna operating in the 5 GHz wireless local area network (WLAN) band. And a 1x4 linear array is also proposed. Based on measured results, the 10-dB impedance bandwidth of the element and array is up to 27.6% and 25%, respectively, and the 5.2 dBi and 11.1 dBi maximum gain is achieved. Meanwhile, the ±30 degrees beam steering is realized by using two beam- forming modules. The proposed antenna and array can be used in FTTR applications.
