Terahertz transceivers

The invention relates to a terahertz transceiver, comprising at least a first and a second antenna (111, 112), wherein the first and/or the second antenna (111, 112) is a dipole antenna comprising a dipole section (113, 114), wherein the dipole section (113, 114) has a gap through which light can be radiated onto the photoconductive material, and wherein a first ending of the dipole section (113, 114) is connected to a first feedline (119a, 120a) and a second ending of the dipole section (113, 114) is connected to a second feedline (119b, 120b), the feedlines (119a, 119b, 120a, 120b) extending with an angle to the dipole section (113, 114). According to the invention, the first and/or the second antenna (111, 112) has an asymmetric design, wherein a first section of at least one of the feedlines (119a, 119b, 120a, 120b) extending on one side of the dipole section (113, 114) is longer than a second section of the at least one feedline (119a, 119b, 120a, 120b) extending on the other side of the dipole section (113, 114) and/or at least one of the feedlines (119a, 119b, 120a, 120b) extends on one side of the dipole section (113, 114), only.
