“…Producing multiple beams in several planes could be easily achieved by arraying the patch feeders in different directions in the xy‐plane of Figure 1. This seems more difficult to attain in the configurations presented in References 12 and 13, which are conceived for azimuthal coverage. Regarding other works like, 20,22 this multi‐beam capability can be attained straightforwardly.…”

“…In order to contextualize the obtained results, a comparison with other works in the literature is shown in Table 3. The antenna in Reference 12 consists in 15 hemispherical lenses placed around a cylindrical support, thus providing full coverage of the azimuth plane. This is a very attractive solution for base station communications, though it only provides multi‐beam capability in one plane.…”

“…This is a simple solution that avoids designing an array and its feeding network, although the impedance matching is limited due to the presence of the dielectric on top of the feeder. Nevertheless, if several of these lens elements are placed on a conformed surface, a multi‐beam antenna can be achieved covering the full azimuth plane 12 . Another option to cover a wide angle with several directive beams is to design a cylindrical Luneburg lens and place several feeders on its side.…”

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.

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.

“…In [17], a 3D printed extended hemispherical lens at 60 GHz has been discussed. Apart from that, the beam switching antennas using dielectric lens have been investigated for different applications [18][19][20][21][22]. However, none of the reported structures has been investigated under BAN application scenario.…”

This paper presents a 3D printed extended hemispherical lens antenna for Body Centric Communications in 60 GHz band. The prototype consists of a 3D printed lens made of Polylactic Acid with three planar broadside patch antenna elements used as a source for the lens. The direction of the main beam antenna is switched by changing the excitation of source elements. The measured overlapping impedance bandwidth of the fabricated antenna is from 57.27 GHz to 60 GHz with reflection coefficient better than −10 dB. The main beam direction switches in broadside direction with 3 dB angular coverage from −29.2 • to +30 • by changing the radiating elements at 60 GHz. The measured gain is 15.28 dBi at 60 GHz. The beam switching capabilities and high gain with broadside radiation characteristics make the proposed antenna a suitable candidate for off-body links at 60 GHz. The effect of placing the antenna structure over the body is also studied in this paper. The body to off-body link measurement is successfully demonstrated with extended lens over the body and an open-ended waveguide as an external node.
