Title:
ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2014195232
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce RCS in an antenna front direction over a plurality of bands (or a wide band) inside and outside of an antenna operation band in simple configuration in an array antenna device formed from a plurality of elements antennas formed on a dielectric substrate including a ground conductor plate on a rear face.SOLUTION: An array antenna device is configured by disposing an outer peripheral portion of a ground conductor plate 11 on which element antennas 3 are not arrayed, around an array antenna part formed by arraying element antennas 3 on a dielectric substrate 2 including the ground conductor plate 11 on a rear face, providing a step, in the outer peripheral portion, having a desired distance outside of an operation band with respect to an antenna opening surface of the array antenna part, and loading a re-radiation wave dedicated module 13 including amplitude phase control means for reception waves on a post-stage of element antennas in a portion of the array antenna part.
