    • A re-entrant resonant cavity (12) includes three parts (18, 19) and (20) which may be manufactured as metallized plastic components. The three parts (18, 19) and (20) are soldered to a multilayer PCB (23) using surface mount technology. The re-entrant stub (16) is in two portions with dielectric material provided by the PCB (23) between them. The cylindrical wall (13) surrounding the stub (16) is also divided into two sections (21) and (22) by the PCB (23). Vias (24) and (25) electrically connect the parts separated by the PCB (23). The pattern of the vias (24) and (25) determines the inductance of the cavity, and hence its resonance frequency. This enables cavities with the same geometry to be operated at different resonance frequencies by using different configurations of through connects. One of the sets of vias may be omitted in some cavities.

    • The disclosed invention relates to a device to efficiently realize (that is, with low dissipative loss) a large variable phase shift in a millimeter wavelength electromagnetic wave. Accordingly, a phase shifter device (1) is disclosed which comprises an axially extended waveguide (2) with a cavity (20) for conducting the electromagnetic wave, a MEMS-actuation mechanism (3), and a plurality of conductive fingers (4, 4a, 4b) which - due to their mechanical movement by means of the MEMS-actuator (3) - adjust a distributed electrical capacitance in the waveguide (2) and thus cause the adjustable phase shift to the electromagnetic wave. Specifically, at least two conductive fingers (4a, 4b) are arranged at an axial distance in a side wall (22) of the waveguide (2). By rotating opposing ends of these fingers into the cavity (20) of the waveguide (2) towards the opposing surface, which can have a predefined elevation profile, a large adjustable phase shift is achieved due to the distributed interaction between the fingers and the electromagnetic wave. Furthermore, by integrating the MEMS device directly into an air-filled metallic waveguide, a low-loss, high-power handling system is realized.
