SCANNING ANTENNA AND METHOD FOR MANUFACTURING SCANNING ANTENNA

WIPO Patent Application WO/2020/121877

A1

A scanning antenna according to the present invention has: a transmission/reception region (R1) including a plurality of antenna units (U); and a non-transmission/reception region (R2) outside the transmission/reception region. The scanning antenna has: a TFT substrate (101); a slot substrate (201); a liquid crystal layer (LC); a seal section (73a) surrounding the liquid crystal layer; a wall-shaped structure (additional seal section) (76A) disposed in a region of the non-transmission/reception region, said region being surrounded by the seal section; a reflecting conductive plate; a first spacer structure for specifying a first gap between a first dielectric substrate (1) and a second dielectric substrate (51) in the transmission/reception region; and a second spacer structure that specifies a second gap larger than the first gap and that is disposed in the wall-shaped structure. The wall-shaped structure has a first principal side surface (79a) and a second principal side surface (79b) that intersect a surface of the first dielectric substrate. When viewed in a normal direction of the first dielectric substrate, at least one of the first principal side surface and the second principal side surface has a plurality of recessed sections and/or a plurality of protruding sections.
