A cavity resonator having temperature compensation which comprises a pot and a cover, which together enclose a cavity resonance volume. The pot comprises a first material, which has a first temperature expansion coefficient and the cover comprises a second material, which has a second temperature expansion coefficient. The second temperature expansion coefficient is greater than the first temperature expansion coefficient, and an expansion of the pot and a deformation of the cover results upon a temperature increase, which each independently and also together cause an enlargement of the cavity resonance volume. Simultaneously, the resonance frequency remains essentially constant.

Disclosed is a method for removably connecting two groups of individual, parallel fibers that are delimited by end faces that are perpendicular to the fiber axis. The two groups of fibers are moved towards each other in an axial direction until each of the fibers abuts against the end face of the assigned fiber from the other group. The fibers of the two groups are aligned in pairs relative to each other before being moved into contact with each other, and any differences in fiber lengths is compensated for by elastically deforming the fiber along the fiber main axis. This method eliminates the disadvantages associated with bending the fibers because length variations are essentially compensated for by axially compressing the fibers.

An antenna () having an emitter element which is positioned in front of a conductive reflector () and has a three-dimensional cast part. The cast part is implemented as conductive and has a closed peripheral structure () having alternating constrictions and bulges. The peripheral structure () spans an imaginary surface () which is intersected by at least two planes of symmetry () of the cast part. At least two fastening elements () are provided, which extend essentially perpendicular to the imaginary surface () and support the peripheral structure () at two points which lie on one of the planes of symmetry (). At the lower ends (), the fastening elements () are connected to the reflector (), the fastening elements () also being used for electrical excitation of the emitter element.
