Title:
ELECTROMAGNETIC WAVE SHIELD
Document Type and Number:
WIPO Patent Application WO/2023/003032
Kind Code:
A1
Abstract:
An electromagnetic wave shield 1a comprises a plate-shaped base portion 5, a plurality of first projecting portions 11, and a contacting portion 5f. The base portion 5 has a first surface 10 and a second surface 20. The first surface 10 is a surface on which electromagnetic waves are to be incident. The second surface 20 extends along the first surface 10 in a position separated from the first surface 10. The plurality of first projecting portions 11 project from the first surface 10 in the opposite direction to the second surface 20. The electromagnetic wave shield 1a contains a dielectric. The electromagnetic wave shield 1a can be attached to a member different from the electromagnetic wave shield 1a, in a state in which the member is in contact with the contacting portion 5f and the first surface 10 is facing the member. The electromagnetic wave shield 1a has a second projecting portion 21a at a specific site 10p. At the specific site 10p, a distance from the contacting portion 5f in a direction parallel to the first surface 10 is the same as a first distance d1 between the first projecting portion 11 closest to the contacting portion 5f and the contacting portion 5f, or is less than the first distance d1.
