A circular conductive plate (1) has an arcuate slit (2). A sector-shaped conductive plate (3.1) having mutually different contours, is movably supported over the circular plate (1) via a dielectric foam spacer (4), such that the origin of the radial vectors of the two plates (1,3) lie on the same axis. The circular plate (1) is supported over a coaxial waveguide structure (6) whose inner and outer conductors (6.1,6.3) are connected to the circular plate (1). |
