US 2026/0128514 A1 · MULTI-STACK ANTENNA

Abstract

Aspects provided herein provide a multi-stack phased antenna array that includes multiple antenna-element layers, each having a matrix of individual antenna elements. The antenna-element layers are separated by at least one dielectric layer and are electrically connected to a modular ratio-combining engine configured to perform maximum-ratio combining across the layers. The combining engine aligns signals in time and phase to maximize in-phase signal strength and may apply amplitude weighting based on signal characteristics. The array supports bidirectional operation for transmit and receive paths and may be used with a base-station transceiver to provide combined uplink and downlink signals. Structural arrangements such as inter-layer spacing, layer alignment, and dielectric thickness may be selected to control polarization, beamwidth, and sidelobes.
