Title:
DEVICE FOR FILTERING ELECTROMAGNETIC WAVES
Document Type and Number:
WIPO Patent Application WO/2010/073486
Kind Code:
A1
Abstract:
A device for filtering electromagnetic waves is provided with: a shield conductor (1); a shield opening (2) provided in the shield conductor (1); a plurality of strip conductors (11), which are connected at the both ends to the shield conductor (1) and divide the shield conductor (1) into a plurality of openings (12); and a plurality of stub conductors (13) arranged on the strip conductors (11) at predetermined intervals, respectively. Each stub conductor (13) passes through electromagnetic waves at a predetermined frequency in the device for filtering electromagnetic waves without substantially affecting radiation of the electromagnetic waves at the predetermined frequency, by preventing a current at a predetermined frequency from flowing in each strip conductor (11) due to the electromagnetic waves which are at the predetermined frequency and passing through the device for filtering electromagnetic waves.
