Dual-polarised lens feed arrays and end-fire antennas in E-band

The growing subscriber demand for better mobile broadband experiences is encouraging the industry to look ahead at the future 5G networks: how can they be readied to meet extreme capacity and performance demands for both access and backhaul applications. The large bandwidth of spectrum available in E-band (71-76 GHz & 81-86 GHz) makes for an attractive resource to support such capacity gains. One of the numerous challenges that face the developers of commercial E-band solutions is how to efficiently implement dual-polarised antennas needed to support dual-stream MIMO applications. This paper presents a novel dual-polarised feeder array for dielectric lens antennas useable for access and backhaul applications as well as a dual-polarised end-fire antenna solution suitable to expand the field of view for user devices.
