Title:
ANTENNA DEVICE
Document Type and Number:
Japanese Patent JP2023147489
Kind Code:
A
Abstract:
To provide a method for further reducing RCS of an antenna device in order to solve a problem that a method for restraining reflection of a radio wave to an irradiation source by absorbing the radio wave with a flat type radio wave absorber to reduce RCS of an antenna device has been proposed, but an effect of reducing RCS has not been sufficiently obtained by only the radio wave absorption of the radio wave absorber.SOLUTION: A antenna device arranged so as to face in a direction in which the antenna device directly faces a radio wave 1000a incoming from the outside includes an antenna 101 arranged for the radio wave 1000a, a structural member 102 that is installed in a direction opposite to the radio wave 1000a and supports the antenna 101, a radio wave scattering structure 103 which is installed on the structural member 102 on the radio wave 1000a side and has unevenness, and a radio wave absorber 104 that fills the unevenness of the radio wave scattering structure 103 on the radio wave 1000a side.SELECTED DRAWING: Figure 1
