Abstract: A description is given of a microwave component which includes a microwave conductor arrangement for conducting electromagnetic waves and a gyromagnetic material which is provided in operative contact with the electromagnetic waves and can be subjected to a magnetic field of adjustable field strength in that the gyromagnetic material, at least one magnet for generating the magnetic field, and a magnetic tuning member, whose magnetic conductivity can be varied in order to adjust the magnetic field strength, are arranged in a magnetic circuit.

Abstract: A microwave component is described with a microwave guiding arrangement for conducting electromagnetic waves and with a gyromagnetic material which is arranged in operational connection with the electromagnetic waves and which can be energized by a magnetic field of adjustable field strength in that the gyromagnetic material, at least one magnet for generating the magnetic field, and a geometrically changeable magnetic tuning element are arranged in a magnetic circuit, said tuning element having a changeable magnetic permeance for the purpose of tuning the magnetic field strength.

Abstract: A microwave component is described with a substantially tub-shaped housing part which comprises a bottom portion and at least one wall portion merging into the circumference of the bottom portion, and with a lid part, said housing part and lid part being formed from a magnetically permeable material and enclosing an inner space in which a number of substantially disc-shaped components are provided in a stacked arrangement between the bottom portion and the lid part such that a partial space of the inner space adjoining at least a sub-portion of the bottom portion is left open by the stacked arrangement.A compact construction benefiting miniaturization is obtained in this microwave component in spite of the accommodation of a bulky load impedance.

Abstract: A microwave element is described with a substantially trough-shaped housing part having a bottom portion and at least one wall portion merging into the circumference of the bottom portion. A lid part, together with the housing part, encloses an inner space in which a number of substantially disc-shaped components are present in a stacked arrangement between the bottom portion and the lid part. The microwave element renders possible an inexpensive manufacture without sacrificing any operational properties. The housing part and the lid part are each formed as an integral part without any cutting operation from a magnetically permeable material. The lid part is directly connected to the housing part by matching and mutually retaining shapes. A magnetically impermeable spacer element is arranged adjacent to the stacked arrangement of the disc-shaped components.

Abstract: A dipole exciter for an antenna for the transmission of electromagnetic waves which is arranged on the free end of a rigid co-axial line is described. The dipole consists of two flat metal pieces (10, 11) which are arranged on the outer conductor (6) of the line and the main dimension of which extends at right angles to the axis of said line.
