Title:
ELECTROMAGNETIC FIELD BAND STOP FILTER
Document Type and Number:
Japanese Patent JP2018174449
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic field band stop filter capable of easily designing frequency characteristics in a compact size.SOLUTION: An embodiment provides an electromagnetic field band stop filter. The electromagnetic field band stop filter has plural unit cells each having reflection characteristics to an electromagnetic wave of specific frequency. Each of the unit cells has plural conductor parts which are disposed in a non-contact manner from each other along the sides of a polygon and a conducting portion for conducting the plural conductor parts. The conductor parts of the plural unit cells are regularly disposed two-dimensionally being neighboring to each other at a distance at which the frequency is reflected.SELECTED DRAWING: Figure 1
