“…In that sense, the amplitude of the E-field must be analyzed at the lens aperture (𝐸 (𝜌)) following the scheme in Figure 3. This aperture E-field directly depends on the feeder gain pattern 𝐺 (𝜃), which can be analytically characterized by using (6). The index n will be defined according to the kind of antenna feeder, and revolution symmetry around 𝑧̂ axis is considered (feeder radiation patter only depends on 𝜃).…”

“…On the other hand, the fifth-generation standard (5G) brings novel concepts to use MBAs because of their ability to produce multiple parallel, but independent, sharp beams with a high gain value to cover a given angular range. In addition, MBAs for base stations with fan-shaped beams are a key element in terrestrial communications due to their gain and reduced interferences [ 3 , 4 , 5 , 6 ].…”

Two types of cost-efficient antennas based on dielectric gradient index dielectric lens have been designed for 5G applications at . The first is a linearly polarized flat lens antenna (LP-FLA) for terrestrial 5G communications. The second is a novel circularly polarized stepped lens antenna (CP-SLA) for 5G satellite services. An efficient design method is presented to optimize and conform the lens topology to the radiation pattern coming from the antenna feeder. The LP-FLA is fed by a traditional linearly polarized pyramidal horn antenna (PHA). The CP-SLA is fed by an open-ended bow-tie waveguide cavity (BCA) antenna. This cavity feeder (BCA), using cross-sections with bow-tie shapes, allows having circular polarization at the desired frequency bandwidth. The two types of presented antennas have been manufactured in order to verify their performance by an easy, low-cost, three-dimensional (3D) printing technique based on stereolithography. The peak realized gain value for the flat (LP-FLA) and stepped (CP-SLA) lens antennas have been increased at to and , respectively, by disposing the lens structures at the appropriated distance from the feeders. Likewise, using an array of horns (PHA) or open-ended bow-tie waveguide cavity (BCA) antenna feeders, it is possible to obtain a maximum steering angle range of 20° and 35°, for a directivity over and , in the planar and stepped lens antennas, respectively.

“…Terrestrial communications usually make use of base stations that divide the surrounding area in angular sectors. The base‐station antennas are commonly linear arrays that provide a fan‐shaped beam, wide enough to cover the azimuth width of a sector and narrow in the elevation plane to increase the directivity and thus the link budget 1,2 . In the case of satellite communications, multi‐beam antennas generate several spots on the Earth to provide service to different regions 3,4 .…”

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.
