Abstract
The present invention provides an antenna in which, on a dielectric substratehaving a back face on which a grounding conductor plateis disposed, a plurality of conductor elementsare arranged in a matrix of rows and columns. Each of the dielectric elementshas a size which cannot function as an antenna. Above the conductor elementsa connecting elementoverlapping two adjacent conductor elementsis disposed. Among the connecting elementssome cause the conductor elementson both sides to be in a conductive condition, and others cause the conductor elementson both sides to be in a non-conductive condition. The switching between the conductive and non-conductive conditions between the conductor elementscan be dynamically performed by a switching element.
