A 1-D Steerable Beam Slotted Waveguide Antenna Employing Non-Conventional Aperiodic Array Architecture for mm-wave Line-Of-Sight MIMO
Paper i proceeding, 2019

Abstract—A 9×9 line-of-sight MIMO test setup is presented.
The slotted waveguide (WG) antenna as designed for this setup
achieves low side-lobe levels (SLLs) in all planes for multiple
scanned beams, while minimizing the loss in antenna efficiency
and bandwidth limitations. The aperiodic arrangement of several
parallel ridge WGs in the E-plane – each with a different
number of equally-spaced and equally-excited radiating slots
along the H-plane, and each possibly integrated with its own
TX/Rx module – has been optimized through a Compressive
Sensing approach. This results in 160 slots organized in 16
columns offering 29 dBi peak gain at a 27.5-31.5 GHz band with
a ±10◦ scan range in the E-plane for the ETSI Class-II-compliant
beams. The measurements of 12 identically beamformed antenna
prototypes for the broadside beam confirm the expected high
antenna efficiency (70–90%), and low input impedance mismatch
over the entire operating bandwidth.
