Title:
ANTENNA DEVICE AND SURFACE-CURRENT-SUPPRESSING FILTER PROVIDED TO SAID ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/021372
Kind Code:
A1
Abstract:
 A surface-current-suppressing filter (1) is a band-stop filter for suppressing the propagation of surface current in a prescribed propagation direction on a dielectric substrate (2). The filter (1) has a structure in which a plurality of electromagnetic band gap (EBG) rows (10, 20) are arranged in the arranging direction. Each of the EBG rows (10, 20) has at least one EBG (11, 21) arranged in the perpendicular direction, which intersects the arranging direction at a right angle. The cutoff characteristics of a first EBG (11) in the first EBG rows (10) differ from the cutoff characteristics of a second EBG (21) in the second EBG rows (20).
