Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/023933
Kind Code:
A1
Abstract:
One aspect of the present invention is an antenna device comprising N antenna elements (where N is an integer of 3 or more) that receive sound waves or radio waves, wherein the antenna elements are each disposed in such a position that a steering vector corresponding to an incident angle θ of one sound wave or radio wave and a steering vector corresponding to an incident angle θ_d ( where θ_d is -π/2 to +π/2) of another sound wave or radio wave are not linearly dependent.
