|Title:||SCANNED ANTENNA AND METHOD OF INSPECTING SCANNED ANTENNA|
This scanned antenna is provided with a TFT substrate having a plurality of patch electrodes (15), a slot substrate having a slot electrode (55), and a liquid crystal layer provided between the TFT substrate and the slot substrate. The slot electrode (55) includes a plurality of slots (57) disposed corresponding to the plurality of patch electrodes 15, and solid portions (56) in which the plurality of slots (57) are not formed. When viewed from a direction normal to the substrate, in each of a plurality of antenna units the patch electrodes (15) are disposed in such a way as to cross the slots (57) in a first direction and to overlap the solid portions (56) on either side of the slots (57). When viewed from the direction normal to the substrate, in at least some antenna units from among the plurality of antenna units, at least one of the peripheral edges of the solid portions (56) and the peripheral edges of the patch electrodes (15) have recessed portions (81, 82) or protruding portions.
