A 4-port stacked-patch microstrip antenna is used as feeder of a perforated flat lens. Each feeder is placed in a different position with respect to the lens, yielding four high-directivity independent beams. The beams cover an angular range from broadside to a 30-degree steering with a gain over 18 dB. The antenna has been implemented by low-cost processes, employing Printed Circuit Board fabrication for the feeder and 3D printing for the lens.},

	abstract = {Abstract 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{\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.},
