  • DIELECTRIC WAVEGUIDE
    Publication number: 20240178540
    Abstract: A dielectric waveguide to transmit an electromagnetic signal, comprises: a first conductor region and a second conductor region. The first and second conductor regions extend along a longitudinal axis of the dielectric waveguide, wherein the first conductor region is formed from a first thermoplastic material and the second conductor region is formed from a second thermoplastic material. The first thermoplastic material has a higher effective permittivity than the second thermoplastic material.

  • Reconfigurable bandpass filter based on a planar combline filter comprising varactor diodes
    Patent number: 9160045
    Abstract: A reconfigurable bandpass filter including at least a tunable planar combline filter including varactor diodes arranged on a carrier board. For automatic calibration of adjustment of blocking voltage during operation, the reconfigurable bandpass filter includes a filter control offering an external abstracted interface. A memory is connected with the filter control. The memory stores calibration data. For approximating of the best possible filter characteristic, the filter control determines, based on memorized data, the best configuration of tuning voltages. The reconfigurable bandpass filter can be used in the field of secondary radar systems.
