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: A method and apparatus for aperture segmentation are disclosed. In one embodiment, the antenna comprises an antenna feed to input a cylindrical feed wave and a physical antenna aperture coupled to the antenna feed and comprising a plurality of segments having antenna elements that form a plurality of closed concentric rings of antenna elements when combined, where the plurality of concentric rings are concentric with respect to the antenna feed.

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.
