Title:
PERIODIC STRUCTURE
Document Type and Number:
Japanese Patent JP2011109414
Kind Code:
A
Abstract:

To provide a periodic structure capable of suppressing radio wave interference by reflected waves and improving a communication environment.

The periodic structure 10 includes a patch layer 40 provided with a plurality of conductor patches 41, a ground layer 50, an insulating layer 60, and a planar connection conductor 70. By causing the connecting positions of the planar connection conductor 70 be different, two or more kinds of LC resonance circuits are configured. For the two or more kinds of LC resonance circuits, a reflection phase for incident waves having a specified frequency is different for the respective kinds of the LC resonance circuit.
