Title:
RESONANCE STRUCTURE, ANTENNA, WIRELESS COMMUNICATION MODULE, AND WIRELESS COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/045237
Kind Code:
A1
Abstract:
This resonance structure comprises a conductive part, a ground conductor, and a first predetermined number of connection conductors. The conductive part is expanded along a first plane, and includes a plurality of first conductors. The ground conductor is disposed so as to be separated from the conductive part, and is expanded along the first plane. The connection conductors extend from the ground conductor toward the conductive part. At least two of the plurality of first conductors are connected to different connection conductors. The first predetermined number of connection conductors include a first connection pair consisting of two of the connection conductors which are disposed side by side along a first direction included in the first plane, and a second connection pair consisting of other two of the connection conductors which are disposed side by side along a second direction intersecting the first direction and being included in the first plane. The resonance structure is configured to resonate at a first frequency along a first current path, and to resonate at a second frequency along a second current path. The first current path includes the ground conductor, the conductive part, and the first connection pair. The second current path includes the ground conductor, the conductive part, and the second connection pair.
