  • Patent number: 9413074
    Abstract: A method and an arrangement for modeling antenna emission characteristics are disclosed. A slotted microwave waveguide is implemented by separate mechanical modules having slot groups respectively implemented therein. For this purpose, the modules are arranged along at least one first spatial direction, so that the modules sectionally form a part of the delimitation of the waveguide. The waveguide formed can be fed by exciting a waveguide mode and the mode propagates through the interior of the module in the waveguide formed. Screens are arranged in front of the modules, to partially cover the slot groups. Arbitrary emission characteristics can be simulated, wherein no separate feed network is necessary due to the use of a modular waveguide.

  • Patent number: 9270389
    Abstract: A measuring method for analyzing the propagation of electromagnetic navigation signals, wherein at least one representative transmitting unit, having a chronological signal feed scheme unambiguously assigned to the navigation signal, is assigned to each of the navigation signals. The representative transmitting units are at least intermittently operated offset in time. A characteristic transmission-free leader pause duration and transmission-free trailer pause duration or a characteristic transmitting duration is assigned to each representative transmitting unit. An analysis unit is coupled to a receiving unit and a time-dependent amplitude detection is carried out, wherein the time curve of the received amplitude values is analyzed by the analysis unit to assign the representative transmitting unit to timeslots of the received amplitude values.

  • Patent number: 5710564
    Abstract: In order to absorb electromagnetic waves in a measurement chamber, the sidewalls and the ceiling of the chamber are lined with contiguous pyramids (20). The pyramid vertices point into the chamber. The structure element (20) has a frame (22) formed by bars made of an electrically insulating glass fiber material and an outer skin (24). The outer skin is cut out of a surface resistance material web. The surface resistance material web is produced by continuously or almost continuously coating a mechanically flexible support web with an electroconductive layer made of a metallic material.
