ANTENNA DEVICE HAVING END-FIRE DIRECTIVITY
Document Type and Number:
Japanese Patent JP2023069445
Kind Code:
A
Abstract:
To provide an antenna device having low profile and end-fire directivity while using a metasurface structure.SOLUTION: An antenna device 10 has a metasurface structure 15 in which a plurality of conductor elements 200 are arranged on one plane of the dielectric substrate 20, and an antenna excitation element 100 that is provided within a predetermined distance separated from the plane. The plurality of conductor elements 200 are arranged symmetrically with respect to the antenna excitation element 100 in the plan view of the dielectric substrate 20.SELECTED DRAWING: Figure 1
