Title:
ARRAY ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/064430
Kind Code:
A1
Abstract:
An array antenna device is provided with: a first dielectric board (1) on the front surface or back surface of which a first conductor ground plate (2) is provided; a plurality of patch antennas (3) provided on the first conductor ground plate (2); a plurality of continuity members (4) respective one ends of which are connected to the first conductor ground plate (2) in such a manner that surrounds the respective ones of the plurality of patch antennas (3); and a second conductor ground plate (5) connected to the respective other ends of the plurality of continuity members (4), wherein if the first conductor ground plate (2) is provided on the front surface of the first dielectric board (1), portions of the plurality of continuity members (4) penetrate the first dielectric board (1) and the remaining portions of the plurality of continuity members (4) function as spacers providing an air layer (6) between the first dielectric board (1) and the second conductor ground plate (5), and if the first conductor ground plate (2) is provided on the back surface of the first dielectric board (1), the plurality of continuity members (4) function as spacers providing an air layer (6) between the first conductor ground plate (2) and the second conductor ground plate (5).
