Title:
電磁界バンドフィルタ
Document Type and Number:
Japanese Patent JP6722601
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic field band filter in size-saving, capable of suppressing the radiation of a leakage electromagnetic wave without impairing radio communication performance.SOLUTION: According to one aspect of the invention, there is provided an electromagnetic field band filter. The electromagnetic field band filter includes a unit cell selectively responding to a frequency of an electromagnetic wave. The unit cell includes: a conductor plate; and a slot formed to the conductor plate and serving as an electromagnetic path of a magnetic current induced by the electromagnetic wave. The slot has an extension extending the effective length of the electromagnetic path.SELECTED DRAWING: Figure 1
