The Design of Millimeter-Wave Wideband Multi-Polarization Antenna Array


With the rapid development of wireless communication, the current fourth-generation (4G) wireless cellular system is challenging to satisfy the continuous growth of wireless traffic demands. Millimeter-wave (mmWave) band has abundant spectrum resources, and a large number of studies on the fifth-generation (5G) wireless communication show that mmWave technology will become the key to the improvement of data transmission rate and capacity in the future.
In this talk, some of our recent work in mmWave wideband multi-polarization antenna array will be introduced. A broadband dual-polarized end-fire mmWave antenna array with a complete GND for 5G communication terminals is presented. The H-P and V-P radiation performance are realized by using electric dipole and SIW cavity, respectively. The measured results show that the impedance bandwidth is 24-29.5 GHz (20.6%). Then, a dual-band dual-circularly polarized magneto-electric dipole antenna array for full-duplex communication systems is presented. The proposed array can simultaneously achieve left-hand circular polarization (LHCP) around 20 GHz and right-hand circular polarization (RHCP) around 30 GHz with a low loss feed network using the printed ridge gap waveguide (PRGW). Finally, the talk will end with the future development trend of mmWave wideband multi-polarization antenna array.
