Title:
Antenna
Document Type and Number:
Japanese Patent JP5915857
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna which inhibits temperature rise of a ferrite substrate used as a shield member.SOLUTION: An antenna of the invention comprises: a substrate having a main surface provided with a conductive part 330 where linear line conductive parts 333 and curved line conductive parts 334 are mixed; a ferrite substrate 280 that is disposed in parallel with the main surface so as to be spaced a predetermined distance away from the substrate in a vertical direction; and an aluminum substrate 290 that is disposed in parallel with the main surface so as to be spaced a predetermined distance away from the ferrite substrate 280 in the vertical direction. Special process parts are provided at portions in the ferrite substrate 280 or the aluminum substrate 290 in which projections of the curve line conductive parts 334 are formed in a perpendicular direction of the main surface.
