Definitions

  • the invention relates to a receiving device for microwave signals with a receiving antenna and a detector circuit.
  • Microwave signals are usually transmitted wirelessly using special antennas and evaluated, demodulated, mixed, amplified, etc. by electronic receivers.
  • the transmit and receive antennas are designed as horn, parabolic antennas or in planar microwave stripline technology.
  • microwave stripline technology has become more and more popular because it enables miniaturized microwave circuits to let.
  • Such a strip line consists of a conductive base area, a dielectric carrier material (substrate plate) arranged above it and a metallized conductor track located thereon.
  • the lines known from high-frequency technology with 50 ⁇ characteristic impedance can also be realized on ceramic substrates.
  • microwave strip lines compared to coaxial or hollow lines, which are largely due to ohmic losses, partly to dielectric losses and, in the case of unshielded circuits, to radiation losses, are largely compensated for by the shorter line sections.
  • the behavior of idling strip lines to emit electromagnetic waves can be used to manufacture planar antennas. Most commonly used are microwave stripline resonators of length ⁇ / 2.
  • a receiving device constructed in an integrated form is supplied with energy from outside by strong microwave radiation via planar antennas in stripline technology
  • a receiving device should therefore be created which only has two signals which are closely adjacent in frequency with one antenna receives and processes with very different amplitudes and different types of polarization.
  • the use of only one antenna for the signals which differ in frequency, amplitude and polarization results in a simple, space-saving and inexpensive construction in the receiving device according to the invention.
  • the entire arrangement can be integrated even more easily, so that all system functions can be accommodated on one module (substrate plate) (see FIG. 1).
  • a division of the transmission into horizontally and vertically linearly polarized waves and the separate decoupling of the two received signals (energy signal and data signal) results in a doubling of the reception channels.
  • the power signal is a hundred times larger than the data signal - and the close frequency neighborhood of the transmitted signals, the decoupling is very good and the reception quality is high. Further advantages are evident from the description below.
  • the receiving device according to the invention is illuminated by two signals of almost the same frequency (spacing a few MHz).
  • the amplitudes of the two signals are very different (c. 20 dB).
  • the polarization planes of the emitted signals are shifted from one another by 90 °.
  • An unmodulated strong RF carrier P U of large amplitude is radiated linearly polarized vertically (or horizontally), while an amplitude-modulated information signal P M of small amplitude is radiated horizontally (or vertically) linearly polarized.
  • the operating range of the transmitted signals is approximately 6 GHz.
  • the receiving device consists of an antenna 1 constructed in stripline technology, which receives both the vertically (horizontally) linearly polarized energy signal P U and the horizontally (vertically) linearly polarized data signal P M.
  • the antenna provided for the energy signal P U and the data signal P M is a strip line on a dielectric substrate (usually aluminum oxide ceramic or poly tetrafluoroethylene).
  • the high-frequency signals from the antennas must be decoupled and processed.
  • the RF signals are derived separately via suitable connections on the stripline antenna 1.
  • the receiving energy signal P U is fed to the center connection A of the series connection of two diodes D1 and D2.
  • This diode circuit is used for rectification and, in conjunction with capacitors (not shown), for voltage doubling and is intended to enable a high output voltage U B at terminals B and C of the series circuit.
  • a rectifier circuit with only one diode is of course also possible.
  • An unmodulated DC voltage is thus applied to terminals B and C, which can be used, for example, to supply power to active components.
  • the data signal P M received by the antenna 1 and offset by 90 ° lies a few MHz next to the energy signal P U , is weaker by a factor of 100 than the energy signal P U and is amplitude-modulated.
  • the received signal is rectified at diode D3 and is available at terminal D as a modulated DC voltage U M.
