Frequency selective surface, antenna, wireless communication device, and radar device

Abstract

In order to implement a frequency selective plate designable in any shape and size; and an antenna, a wireless communication device, and a radar device including a frequency selective plate designable in any shape and size, a frequency selective plate according to the present invention is a frequency selective plate for transmitting an electromagnetic wave of a predetermined frequency, and reflecting an electromagnetic wave of a frequency other than the predetermined frequency. The frequency selective plate includes at least one or more conductive closed loops configured in such a way that a conductive pattern formed on one layer, and a conductive pattern to be formed on at least one layer different from the one layer are electrically connected by a connecting portion.
