“…To date, though, development of agile 2D beamforming systems has been limited, focusing on simulation of very large digital beamforming computational systems 11,12 or smallerscale customized hybrid analog and digital solutions. [13][14][15] This article presents a compact passive SIW beamforming network for the exact purpose of feeding a planar antenna array system at 60 GHz. In this article, the preliminary Butler matrix design used in Ref.…”

A 4x4 substrate integrated waveguide (SIW) Butler matrix for two‐dimensional (2‐D) beam steering operating at 60 GHz is developed and experimentally evaluated in this article. The SIW beamforming network is a Butler matrix that is implemented with new designs of its constituent components in order to achieve a compact design. Namely, an SIW phase shifter that uses periodic rectangular slots is introduced for the first time at 60 GHz to replace the more area‐consuming meandered SIW. The phase shifter prototype, fabricated and measured as a proof of concept, demonstrates achieving an additional 20.3° of phase shift with using only 3 apertures without increasing the length or meandering the SIW line. The hybrid coupler and crossover sections of the SIW Butler matrix are also optimized to reduce the overall area of Butler matrix by 53.9%. The SIW Butler matrix prototype is fabricated and measured demonstrating achieving the differential output phase values needed to switch the beam of a 2‐D array in four quadrants while keeping the insertion loss magnitude imbalance of below 1.47 dB from simulations and 3.34 dB from measurements.

“…An example is found in [2], where an Acrylonitrile Butadiene Styrene (ABS) 3D-printed lens is proposed as beam focusing solution at 60 GHz, but without steering capabilities. For the current band of operation (24-30 GHz), other solutions may be found as in [3][4][5] but they usually imply complex architectures, low gain (below 20 dB) or scanning is not continuous. In this paper, a inexpensive and simple solution is proposed to overcome most of those issues.…”

A switchable multi-antenna architecture for lensassisted beamsteering in the Ka-band region allocated for 5G communications (24-30 GHz) is proposed. The radiating elements are bow-tie antennas mounted with a 3D printed highpermittivity dielectric lens (εr = 10). A 5-element array is simulated showing switchable 30 • beam steering over a 120 • sector with 19 dB maximum gain. Single antenna measurements of a scaled prototype with a Polylactic Acid (PLA) lens (εr = 2.7) show gains around 11 dB, in agreement with projected performances.
