A planar dielectric lens has been designed for low‐cost multi‐beam antennas in the 26‐GHz band of 5G communications. The lens feeder is a stacked‐patch microstrip antenna with four input ports, thus permitting four independent high‐directivity radiation beams. Maximum steering of 25° can be attained, which a simulated gain over 18 dB for all scanning angles. The antenna has been implemented with low‐cost manufacturing techniques. The feeder is fabricated as a printed circuit board, while the lens is realized as a perforated 3D‐printed dielectric piece. Experimental results confirm the multi‐beam capability of the lens system, suggesting that the spillover efficiency can be improved in further works.
