Abstract
A scanned antenna () is a scanned antenna including antenna elements (U) arranged together, the scanned antenna including: a TFT substrate () including a first dielectric substrate (), TFTs, gate bus lines, source bus lines, and patch electrodes (); a slot substrate () including a second dielectric substrate () a slot electrode (); a liquid crystal layer (LC) provided between the TFT substrate and the slot substrate; and a reflective conductive plate (). The slot electrode includes slots () arranged so as to correspond to the patch electrodes. As seen from the normal direction to the first dielectric substrate, a plurality of spacer structures () provided between the TFT substrate and the slot substrate are arranged so as not to overlap with first regions (Rp) and/or second regions (Rp), where the first regions are regions that are within a distance of 0.3 mm from edges of the slots and the second regions are regions that are within a distance of 0.3 mm from edges of the patch electrodes.
