Abstract: An antenna for electromagnetic waves including a quantum interference filter, at least one low-temperature transistor and primary antenna structures, means for deriving an electromagnetic wave from the circuit, cooling elements and insulating means. The interference filter and the transistor act as active components, the primary antenna structure is connected up to at least one of the active components in such a way that upon incidence of an electromagnetic wave on the primary antenna structure there is present at the output of the at least one active component a conducted electromagnetic wave, and wherein at least one part of the circuit and at least one part of the primary antenna structure are thermally insulated, the thermal insulation is frequency transparent to electromagnetic waves, and the cooling elements are designed to cool down at least one part of the circuit below the transition temperature of at least one of the superconducting materials.

Abstract: A device is proposed for high-resolution measurement, in particular for high-resolution absolute measurement of magnetic fields, having a network (1) of transitions (3) between superconductors (5, 6) which exhibit Josephson effects, called junctions below, the network comprising closed meshes (7, 8, 9, 10, 11, 12, 13), denoted by cells below, which in each case have junctions (3), which junctions are connected in a superconducting fashion, and at least three of these cells being connected in a superconducting and/or nonsuperconducting fashion. The object of the invention consists in further developing this device in such a way that it is possible to make absolute measurements of magnetic fields in a highly sensitive fashion.
