Abstract: Examples disclosed herein relate to a high gain relay antenna system that includes a first passive reflect array configured to receive electromagnetic radiation from a transmitting source and generate a transmit beamforming signal with a first gain from the electromagnetic radiation. The high gain relay antenna system also includes a second passive reflect array positioned at a predetermined distance from the first passive reflect array and configured to collimate phases of the transmit beamforming signal from the first passive reflect array and transmit an outbound beamforming signal with a second gain greater than the first gain, to a coverage area. Other examples disclosed herein relate to a dual-reflect array system and a method of high gain relay with multiple passive reflect array antennas.

Abstract: Examples disclosed herein relate to a meta-structure based reflectarray for beamforming wireless applications and a method of operation of passive reflectarrays in an indoor environment. The method includes receiving, by a plurality of passive reflectarrays, a Radio Frequency (RF) signal from a source. The method also includes reflecting, by the plurality of passive reflectarrays, the RF signal to generate a plurality of RF beams to a respective target coverage area, in which each of the plurality of RF beams increases a multipath gain along a signal path between a corresponding passive reflectarray to the respective target coverage area.
