Title:
MULTIBAND ANTENNA, WIRELESS COMMUNICATION MODULE, AND WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/159899
Kind Code:
A1
Abstract:
A multiband antenna comprises: a radiation conductor having one rectangular first slit that extends in the second axial direction of a first right-hand orthogonal coordinate system having a first axial direction, a second axial direction, and a third axial direction; a ground conductor disposed separated by a prescribed interval from the radiation conductor in the third axial direction; and a first strip conductor disposed between the radiation conductor and the ground conductor, and extending in the first axial direction, the end of the first strip conductor overlapping with the first slit when viewed from the third axial direction.
