Document Type and Number:
WIPO Patent Application WO/2023/157156
Kind Code:
A1
Abstract:
This antenna device (101A) comprises: an antenna excitation element (12) provided to a surface of a substrate (11); a conductor pattern (13) provided to the surface of the substrate (11) and arranged at the periphery of the antenna excitation element (12) so as not to contact the antenna excitation element (12); a parasitic element (22) provided to a surface of a substrate (21) facing the surface of the substrate (11); and a conductor pattern (23) provided to the surface of the substrate (21) and arranged at the periphery of the parasitic element (22) so as not to contact the parasitic element (22). The conductor pattern (13) and the conductor pattern (23) are electrically connected. The thickness of the conductor pattern (13) is equal to or greater than the thickness of the antenna excitation element (12). The thickness of the conductor pattern (23) is equal to or greater than the thickness of the parasitic element (22).
