Document Type and Number:
WIPO Patent Application WO/2017/130475
Kind Code:
A1
Abstract:
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) formed on a first main surface of the second dielectric substrate; a liquid crystal layer (LC) provided between the TFT substrate and the slot substrate; and a reflective conduction plate (65) arranged so as to face, via a dielectric layer (54), a second main surface of the second dielectric substrate (51) opposite the first main surface. The slot electrode has slots arranged so as to correspond to the respective patch electrodes, and the scanning antenna further includes a heater unit (68) provided outside the TFT substrate (101) or outside the slot substrate (201).
