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.

Abstract: An apparatus for exchanging liquid crystal (LC) between two areas of an antenna array and method for using the same are disclosed. In one embodiment, the antenna comprises an antenna element array having a plurality of radiating radio-frequency (RF) antenna elements formed using portions of first and second substrates with a liquid crystal (LC) therebetween, and a structure between the first and second substrates and outside the area of the RF antenna elements to collect LC from an area between the first and second substrates forming the RF antenna elements due to LC expansion.

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, 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, a first spacer structure defining a first gap between a first dielectric substrate and the second dielectric substrate in the transmission and/or reception region, and a second spacer structure defining a second gap between the first dielectric substrate and the second dielectric substrate in the non-transmission and/or reception region, the second gap being wider than the first gap. The second spacer structure is disposed within the seal portion or within a region surrounded by the seal potion.
