PLANAR ARRAY ANTENNA AND QUASI-MILLIMETER WAVE/MILLIMETER WAVE WIRELESS COMMUNICATION MODULE

Document Type and Number:

WIPO Patent Application WO/2018/021316

Kind Code:

A1

Abstract:

This planar array antenna is provided with: a radiating part 51 having a plurality of radiating conductors 30 and a first ground conductor layer 20; and a power supplying part 52 having a plurality of strip conductors 10 and a second ground conductor layer 60. The plurality of strip conductors 10 are disposed corresponding to the plurality of radiating conductors 30 between the first ground conductor layer 20 and the second ground conductor layer 60. The first ground conductor layer 20 is positioned between the strip conductors 10 corresponding to the respective radiating conductors 30, and has: a plurality of slots 21 extending in a direction crossing the direction in which the strip conductors 10 extend; and a groove or at least one hole 22 positioned between two neighboring slots 21 among the plurality of slots 21.
