Abstract

Design of millimeter-wave arrays for base stations operating in dense urban environment is investigated. Innovative designs for linear subarrays with shaped beam patterns for hybrid beamforming are proposed. The number of elements and element spacings in the subarrays are optimally selected based on a pattern matching technique. The subarrays are designed and verified in series edge-fed slotted substrate integrated waveguide technology at 26 GHz. A novel phase shifter unit is proposed to reduce the subarray width for grating lobe-free beam steering in the plane orthogonal to the sub-array axis. Infinite array simulations are performed to observe the coupling effects on the subarrays.
