	abstract = {A low-cost solution for multi-beam antenna systems is explored for 5G applications in the 26-GHz band. 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.},

	abstract = {The incoming 5G systems propose unprecedented communication capabilities that require a maximization of the channel and spectrum exploitation. Waveguide antenna arrays can play an important role in 5G environments due to their high performance in terms of efficiency and bandwidth. Moreover, higher frequencies appear necessary in order to achieve the requirements of channel capacity and spectrum bandwidth. At millimeter-wave frequencies, new challenges for the design and fabrication of the communication devices are encountered. The feasibility of traditional manufacturing techniques and conventional additive manufacturing processes severely decreases, since part tolerances, assembly, and alignment become critical for the antenna performance. In order to illustrate the possibilities of the diffusion bonding technique applied to waveguide antennas operating in the W-band of 5G systems, a circularly polarized cavity array has been successfully manufactured. This manufacturing process provides the advantages of both traditional and additive manufacturing. A 5.6 percent effective bandwidth at 90 GHz has been experimentally obtained with reflected power under 10 percent, axial ratio below 3 dB, and antenna efficiency over 50 percent.},
