(EN) Scanning antenna
(ZH) 扫描天线
要約
(EN)
A scanning antenna (1000) in which antenna units (U) are arranged includes: a TFT substrate (101) having a first dielectric substrate (1), TFTs, gate bus lines, source bus lines, and patch electrodes (15); a slot substrate (201) having a second dielectric substrate (51) and a slot electrode (55); a liquid crystal layer (LC) provided between the TFT substrate and the slot substrate; and a reflective conduction plate (65). The slot electrode has slots (57) arranged so as to correspond to the respective patch electrodes. In a case in which, when seen from the direction of the normal to the first dielectric substrate, regions within a distance of 0.3 mm from the edges of the slots are treated as first regions (Rp1) and regions within a distance of 0.3 mm from the edges of the patch electrodes are treated as second regions (Rp2), a plurality of spacer structures (75) provided between the TFT substrate and the slot substrate are arranged so as not to be superposed with the first regions and/or the second regions.
