摘要:
A surface-mounted antenna has a base having a substantially rectangular parallelepiped shape, an antenna element formed on the surface of the base and having a first radiation electrode subjected to direct power supply, and an antenna element formed on the surface of the base and having a radiation electrode subjected to capacitive coupling power supply. With this, the smaller surface-mounted antenna of a combo antenna type can be provided.

摘要:
An antenna device has a substrate having a power supply line, and a surface-mounted multiple-resonance antenna having a base and a conductor pattern formed on the base and provided on the substrate, wherein the conductor pattern includes two antenna conductor patterns and a plane conductor pattern which connects each of the antenna conductor patterns and the power supply line, the plane conductor pattern 16 includes a slit which controls the connection distance between at least a portion of each of the antenna conductor patterns and the power supply line, and the substrate does not have a conductor pattern in a region corresponding to the slit.
摘要:
An antenna includes a dielectric substrate and an antenna element, wherein the dielectric substrate has a mark on an outer surface, the mark having a lower relative permittivity than the dielectric substrate, the antenna element is formed from a FPC film, and the FPC film has an antenna electrode on one side and a flexible insulating film with an adhesive layer on the other side and is adhered to the outer surface of the dielectric substrate with a tip or bend of the antenna electrode aligned with the mark.
