PHOTOCONDUCTIVE MULTICHANNEL TERAHERTZ RECEIVING ANTENNA, RECEIVER, TERAHERTZ SYSTEM AND TERAHERTZ METHOD

摘要

The invention relates to a receiving antenna (1) for terahertz radiation (30), comprising an antenna conductor (2) and a first photoconductor (3), which is interconnected with the antenna conductor (2), can be activated by light (9) and, in an activated state, enables an antenna current (28) flowing through the antenna conductor (2) and the first photoconductor (3), characterized in that the receiving antenna (1) has at least one second photoconductor (4), which likewise is interconnected with the antenna conductor (2) and can be activated by light (9), is connected in parallel with the first photoconductor (3) and, in an activated state, enables an antenna current (28) flowing through the antenna conductor (2) and the second photoconductor (4), at least one high-pass filter (8) being connected between each of the photoconductors (3, 4) and the antenna conductor (2). The invention further relates to a receiver for terahertz radiation (30), to a terahertz system and to a method for generating and detecting terahertz radiation (30) using a corresponding terahertz system.
