A device with a cavity resonator comprises a housing (3, 4, 12) made of electrically conductive material. A reflector unit (11), a microwave unit (9) and a partially reflecting reflector unit (5) are provided inside the housing (3, 4, 12), the housing (4) having a radiation opening (13). The reflector unit (11), the microwave unit (9), the partially reflecting reflector unit (5) and the radiation opening (13) are situated on a radiation axis (14), the microwave unit (9) being placed between the reflector units (5, 11). In addition, a distance between the reflector unit (11) and the partially reflecting reflector unit (5) corresponds to half a wavelength to be generated or to be detected or to several times this half wavelength. At the same time, a measurement transversal to the radiation axis (14) is at least one fourth of the wavelength.
