“…A wideband endfire three printing dielectric antenna with designable permittivity has been introduced in Reference 16. In Reference 17, a comb mushroom‐like dielectric lens has been fabricated by three‐dimensional printing, and the lens was used for stable gain enhancement of log‐periodic dipole antenna. In Reference 18, the cylindrical three‐dimensional printing luneburg lens antenna has been reported, and which was used for millimeter wave applications.…”

In this article, a novel lens antenna with wide beamwidth using three-dimensional printing is proposed. The proposed antenna is comprised of a concave lens by using three-dimensional printing, a lantern shaped patch with a parasitic ring, and eight loaded monopoles around the center. The antenna operating frequency is 5.8 GHz, and the prototype is implemented. The measured half power beamwidth are 142 and 130 at the xoz and the yoz planes, respectively. Besides, the antenna is low cost, easy to fabricated, and very low cross polarization. Measured results agree well with the simulation results.

“…More versions of shaped lens have been proposed for beam shaping, 14 mechanical beam reorientation 15 or multi‐beam applications 16 . Thanks to the advances of additive manufacturing, complex lens structures can be now implemented, for instance to achieve flat gain over a wide bandwidth, 17 or integrate the lens with the feeder, in this case a helical antenna 18 . Alternatively, planar lenses are easier to fabricate and provide similar results, although the feeder must be placed at a certain distance from the lens and the overall size increases.…”

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.

Prototypes of a special conformal load‐bearing antenna array (CLAA) which has nondevelopable surface, are designed, fabricated, and tested, and the effect of the substrate curvature radius on its EM performance is also researched in this work. A novel three‐dimensional (3‐D) printing technology and fabrication equipment based on micro‐droplet spraying and metal laser sintering are proposed to create patch array and divider network on a non‐developable curved rigid substrate. In order to compare with conventional technology (such as chemical etching), a planar CLAA prototype with two patches, operating frequency at 5GHz, is designed and fabricated by two different technologies, the surface roughness, fabrication tolerance, and EM performance are tested and compared. Finally, a spherical CLAA prototype with eight patches, operating frequency at 13GHz, is designed and fabricated by the novel 3D printing, measured EM performance demonstrate the applicability of additive manufacturing for this special CLAA.
