Abstract
A scanning antenna including a transmission and/or reception region including a plurality of antenna units arranged in the transmission and/or reception region and a non-transmission and/or reception region includes a TFT substrate including a plurality of first TFTs supported by a first dielectric substrate and a plurality of patch electrodes, a slot substrate including a slot electrode including a plurality of slots, a liquid crystal layer provided between the TFT substrate and the slot substrate, and a plurality of inspection electrode sections disposed while not overlapping the plurality of antenna units when viewed from a normal direction of the first dielectric substrate. Each of a plurality of inspection electrode sections includes a second TFT supported by the TFT substrate and including a source electrode connected to the source bus line and a gate electrode connected to the gate bus line, a transparent electrode supported by the TFT substrate and connected to a drain electrode of the second TFT, and a slot electrode extending while opposing the transparent electrode with the liquid crystal layer interposed therebetween.
