Abstract: A unit cell can be used for a metasurface, metamaterial, or beamforming antenna. The unit cell includes a metal layer attached to a substrate. The metal layer defines an iris opening for the unit cell. One or more tunable capacitance devices are positioned within or across the iris opening. Each tunable capacitance device is to tune resonance frequency of the unit cell. Mass transfer technologies or self-assembly processes may be used to position the tunable capacitance devices.

Abstract: A scanning antenna includes a transmission and/or reception region including a plurality of antenna units and a non-transmission and/or reception region other than the transmission and/or reception region. The scanning antenna includes a TFT substrate, a slot substrate, a liquid crystal layer provided between the TFT substrate and the slot substrate, a seal portion provided in the non-transmission and/or reception region and surrounding the liquid crystal layer, and a reflective conductive plate disposed opposing a second main surface of a second dielectric substrate with a dielectric layer interposed between the reflective conductive plate and the second main surface. The slot electrode includes an opening or a recessed portion formed in the non-transmission and/or reception region and in the region surrounded by the seal portion.

Abstract: Monitoring and compensating for environmental and other conditions affecting antenna elements of an antenna is described. The conditions may affect radio frequency (RF) liquid crystal of the antenna elements. In one embodiment, the antenna comprises a physical antenna aperture having an array of surface scattering antenna elements that are controlled and operable together to form a beam for the frequency band for use in holographic beam steering and a compensation controller to perform compensation on the antenna elements based on monitored antenna conditions.

Abstract: A scanning antenna includes a transmission and/or reception region including a plurality of antenna units and a non-transmission and/or reception region other than the transmission and/or reception region. The scanning antenna includes a TFT substrate, a slot substrate, a liquid crystal layer, a seal portion surrounding the liquid crystal layer, a wall structure (additional seal portion) disposed in a region surrounded by the seal portion in the non-transmission and/or reception region, a reflective conductive plate, a first spacer structure defining a first gap between a first dielectric substrate and a second dielectric substrate in the transmission and/or reception region, and a second spacer structure disposed in the wall structure and defining a second gap wider than the first gap. The wall structure includes a first main side face and a second main side face that intersect a surface of the first dielectric substrate, and at least one of the first main side face and the second main side face includes a plurality of recessed portions and/or a plurality of protruding portions when viewed from a normal direction of the first dielectric substrate.
