Abstract: In embodiments, an apparatus includes a beamformer including a plurality of inputs and a plurality of outputs, a plurality of input vias, and a plurality of output vias. Each input of the plurality of inputs electrically couples to a respective input via of the plurality of input vias. Each output of the plurality of outputs electrically couples to a respective output via of the plurality of output vias. The beamformer is included in a first layer, wherein the plurality of input vias are configured to electrically couple to termination trace ends of a plurality of hierarchical networks provided on at least second and third layers, and wherein the plurality of hierarchical networks comprises at least three hierarchical networks.

Abstract: Examples disclosed herein relate to a power division structure. The power division structure has an input port to receive a transmission signal, a plurality of output ports to transmit portions of the transmission signal to a signal structure, and a plurality of transmission paths to propagate the transmission signal from the input port to the plurality of output ports, each transmission path having an associated weight and configured with power division vias to distribute the transmission signal according to its associated weight.

Abstract: Examples disclosed herein relate to an intelligent metamaterial radar. The radar has an Intelligent Metamaterial (“iMTM”) antenna module to radiate a transmission signal with a dynamically controllable iMTM antenna in a plurality of directions based on a controlled reactance and generate radar data capturing a surrounding environment. The radar also has an iMTM interface module to detect and identify a target in the surrounding environment from the radar data and to control the iMTM antenna module.

Abstract: Examples disclosed herein relate to a smart infrastructure sensing and communication system. The system includes a resonant structure formed of an array of resonant cells and attached to a glass of a smart infrastructure. The resonant structure generates a radio frequency (“RF”) signal that is shaped and steered by the array. A controller is in communication with the resonant structure to receive the RF signal.

Abstract: The present invention is an antenna system having an array of metamaterial cells and a transmission array having a plurality of slots, wherein a signal propagates through the transmission array to the metamaterial cells and radiates a beamform. The system further includes reactance control means to adjust a phase of the beamform and to perform beam steering and beam switching.
