Abstract: Designs and control techniques for passive Multiple-Input Multiple-Output (pMIMO) surfaces are provided. An example array of reconfigurable reflective elements includes a plurality of unit cells each comprising a cross-slot radiating element, a first varactor diode disposed across a first end of the cross-slot radiating element and configured to control polarization in a first plane, and a second varactor diode disposed across a second end of the cross-slot radiating element and configured to control polarization in a second plane, and a controller coupled to the first varactor diode and the second varactor diode and configured to provide control signals to the first varactor diode and the second varactor diode to vary a direction of a reflected signal.

Abstract: An antenna structure is disclosed that includes a first antenna extending from a substrate, a second antenna formed on the substrate, and first and second parasitic elements formed on the substrate. The first antenna provides an omni-directional radiation pattern in the azimuth plane for vertically polarized signals, and the second antenna provides an omni-directional radiation pattern in the azimuth plane for horizontally polarized signals. The parasitic elements absorb and re-radiate electromagnetic waves radiated from the second antenna.

Abstract: A base station is disclosed that includes two separated antenna arrays. In a TDD mode of operation, both arrays are used for either transmit or receive. In a sub-band full-duplex mode of operation, one array is used to transmit downlink symbols while the remaining array is used to receive uplink symbols.
