“…4(a) presents the configuration of the circular microstrip patch antenna designed to illuminate the TA aperture. To achieve a dual-polarization operation, the patch is fed through two U-shaped slots in the center ground plane [24], [25], [26]. The antenna uses a Taconic RF-TLY-5 dielectric substrate (with εr=2.2, tanδ=0.001), with a thickness of 0.254 mm on the patch side and 0.127 mm on the feed microstrip side, where SMPS-type connectors are provided.…”

This article presents an optimized dual-polarized transmitarray antenna (TA) designed for MIMO applications at the Ka-band, capable of switching beams in two directions. The antenna aperture uses a small unit cell with three layers of Taconic RF-35 dielectric substrates, which can be easily fabricated using PCB technology. The unit cell achieved a 360-degree phase shift and a transmission magnitude exceeding -0.4 dB at 28 GHz. We used nine dual-polarized patch antennas in a cross shape, each with a 10.5 dBi gain at 28 GHz, to switch the beams in two directions without changing the feed location. We optimized the phase distribution in the TA aperture and adjusted the feed antenna's F/D and tilt to achieve a high-gain antenna with low-gain roll-off during beam switching. The fabricated TA exhibited excellent agreement with the full-wave simulation results. It achieved ±15 degrees and ±30 degrees beam tilts in the x-and y-directions, with less than 0.8 dB gain roll-off for both polarizations.INDEX TERMS Transmitarray antennas, 2D beam switching, low profile, dual-polarized, gain roll-off

In this paper, the design of a passive multi-beam lens antenna is proposed for the CubeSat space communication system as an alternative application of a 2-D microstrip antenna array that has originally been designed for a 39 GHz 5G MU-MIMO system. The half-ellipsoid lens is 3-D printed using stereolithography (SLA) technology. The antenna prototype is capable of selecting the main beam between 16 different directions with a gain ranging from 14 to 16 dBi and a half-power beamwidth of 14 • to 18 • . The measurements carried out in an anechoic chamber show good agreement with numerical simulations. The presented prototype shows that by employing 3-D printing technologies existing antennas can be easily and inexpensively converted to switched-beam or multi-beam solutions.
