Abstract
A receiver which is configured to detect a terahertz wave incident on a first surface of a substrate, the receiver comprising: an antenna which is provided on the first surface of the substrate and is configured to receive the terahertz wave; and a through electrode which is electrically connected to the antenna and penetrates the substrate from the first surface to a second surface, the second surface being opposite to the first surface, wherein the through electrode is separated from the antenna by a distance that is 0.25 times a resonance wavelength or more.
