ABSTRACT:
In a radio-frequency device in which a dielectric layer, a first conductive layer and a second conductive layer are stacked one on another, the second conductive layer is including a plurality of conductive elements which are arrayed periodically and independently of one another at a specified array pitch, and a plurality of connecting elements for electrically connecting a plurality of mutually neighboring ones of the conductive elements to each other. The connection by the connecting elements is selectively made, thus making it possible to control radiation directivity of an electromagnetic field formed by the first and second conductive layers.
