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{\textdegree} 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.}, keywords = {5G mobile communication, Beam steering, Microstrip antennas}, doi = {10.1002/mop.32486}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1002/mop.32486}, author = {E Garcia-Marin and D S Filipovic and J L Masa-Campos and P Sanchez-Olivares} }
