Abstract: An antenna device, or a method of its manufacture, comprises a photoconductive thin film 202 deposited on a condenser lens 201. A metal electrode 203 is formed on the photoconductive thin film 202 such that it provides an antenna element for generating or detecting terahertz electromagnetic signals. The condenser lens 201 may be a super-hemispherical shape and made of a high-resistive silicon whilst the photoconductive thin film 202 may be made of polycrystalline gallium arsenide (GaAs). The condenser lens 201 may be mounted in a holder which leaves exposed the surface area of the lens on to which the photoconductive layer 202 is to be deposited. The holder may comprise a mounting portion with a concave shape to receive the corresponding shape of the lens 201 and a cover portion with a through hole. The simple antenna device may be provided quickly, effectively and cheaply.

Abstract: Provided are a condenser lens-coupled photoconductive antenna device for terahertz wave generation and detection and a fabricating method thereof. A condenser lens-coupled photoconductive antenna device for terahertz wave generation and detection includes a condenser lens, a photoconductive thin film deposited on the condenser lens, and a metal electrode formed on the photoconductive thin film for a photoconductive antenna. In the antenna device, the condenser lens and the photoconductive thin film are coupled to each other.
