Definitions

  • the invention relates to an antenna for receiving circularly polarized satellite radio signals.
  • Satellite radio signals are transmitted due to polarization rotations in the transmission path usually with circularly polarized electromagnetic waves.
  • program contents are transmitted, for example, in frequency bands closely spaced separate frequency bands. This is done in the example of SDARS satellite broadcasting at a frequency of about 2.33 GHz in two adjacent frequency bands each with a bandwidth of 4 MHz with a spacing of the center frequencies of 8 MHz.
  • the signals are emitted by different satellites with a circularly polarized in one direction electromagnetic wave.
  • circularly polarized antennas are used to receive in the corresponding direction of rotation.
  • Such antennas are for example off DE-A-4008505 and DE-A-10163793 known.
  • This satellite broadcasting system is additionally supported by the regional emission of terrestrial signals in another, arranged between the two satellite signals frequency band of the same bandwidth. Similar satellite broadcasting systems are currently being planned.
  • the satellites of the Global Positioning System (GPS) also radiate circularly polarized waves in one direction at the frequency of approximately 1575 MHz, so that the antenna forms mentioned can basically be designed for this service.
  • the from the DE-A-4008505 known antenna is constructed on a substantially horizontally oriented conductive base and consists of crossed horizontal dipoles with V-shaped downwards inclined, consisting of linear ladder parts Dipolhharn which are mechanically fixed at an azimuthal angle of 90 degrees to each other and attached to the upper end of a fixed to the conductive base linear vertical conductor.
  • the from the DE-A-10163793 known antenna is also constructed on a generally horizontally oriented conductive base and consists of crossed azimuthally mounted at 90 ° to each other frame structures. In both antennas, the mutually spatially offset by 90 ° antenna parts in the electrical phase are interconnected shifted by 90 ° to each other to generate the circular polarization. Similarly, patch antennas act. All of the prior art antennas are less efficient in terms of low elevation angle reception.
  • antenna forms are suitable for the reception of satellite signals, which are emitted by high-flying satellites - so-called HEOS.
  • HEOS high-flying satellites
  • the object of the invention is therefore to provide an antenna which, depending on their design, both for a particularly powerful reception of low-elevation angles incident circularly polarized satellite signals and for the high-power reception of higher elevation angles in incident satellite signals with sufficient gain and high cross polarization suppression can be designed over a large elevation angle range and in particular the possibility of an economical production should be given.
  • the advantage of the invention is associated with the reception of linearly polarized and received at low elevation waves with azimuthally nearly homogeneous directional diagram to enable particularly high profit.
  • the antenna can advantageously in combination with the above-described and from the DE-A-4008505 and the DE-A-10163793 known antennas and patch antennas according to the prior art to a directional antenna with adjustable or dynamically traceable azimuthal main direction in the radiation pattern are designed. This advantage is explained in more detail below.
  • Another advantage of an antenna according to the invention is its particularly simple manufacturability, which allows the realization by simple curved sheet metal structures.
  • the antenna for receiving circularly polarized satellite radio signals comprises at least one substantially horizontally oriented conductor loop arranged above a conductive base surface 6, with an arrangement for electromagnetic excitation 3 of the conductor loop connected to an antenna connection 5.
  • the conductor loop is designed as a ring line emitter 2 by a polygonal or circular closed loop in a horizontal plane with the height h over the conductive base 6 extending.
  • the ring line radiator 2 forms a resonant structure and is electrically excited by the electromagnetic excitation 3 in such a way that the current distribution on the ring line of a running line wave adjusts in a direction of rotation whose phase difference over the extended length of the ring line structure is just M * 2 ⁇ .
  • M is at least two and is an integer.
  • At least one radiator 4 which is vertical on the ring line radiator 2 and extends toward the conductive base surface, is / which is / are electromagnetically coupled to both the ring line radiator 2 and the electrically conductive base surface 6.
  • the height h is preferably less than 1/5 of the free space wavelength ⁇ to choose.
  • Another very important advantage of the present invention results from the property that, in addition to the horizontally polarized ring line emitter 2, at least at one ring line coupling point 7, there is another emitter 4, which has a polarization oriented perpendicular to the polarization of the ring line emitters 2. In the presence of terrestrially vertically polarized signals, this emitter can advantageously also be used to receive these signals.
  • Azimuthal is generally aimed at broadcasting.
  • the distribution of the currents on an antenna in receive mode depends on the terminator at the antenna junction.
  • the distribution of the currents on the antenna conductors relative to the supply current at the antenna connection point is independent of the source resistance of the supplying signal source and is thus clearly linked to the directional diagram and the polarization of the antenna.
  • the object of the invention with respect to polarization and radiation patterns on the basis of the design of the antenna structure for generating corresponding currents in the transmission mode of Antenna solved.
  • the object of the invention for the receiving operation is solved. All considerations made below about currents on the antenna structure and their phases or their phase reference point thus refer to the reciprocal operation of the receiving antenna as a transmitting antenna, unless the receiving mode is specifically addressed.
  • FIG. 1 shows the basic form of an antenna according to the invention with a designed as a resonant structure circular loop emitter 2 for generating a circularly polarized field.
  • a resonant structure circular loop emitter 2 for generating a circularly polarized field.
  • M represents an integer and M assumes at least the value 2.
  • a further advantage of an antenna of this kind is that the phase of the circular polarization is rotated with the azimuthal angle of the propagation vector in M-times and thus in at least 2-fold dependence.
  • an antenna of this type can be combined with a crossed radiator 24 of the same center Z according to the prior art to a directional antenna with an azimuthal main direction.
  • the directivity with azimuthal main direction results from the combination of the radiation diagram of the crossed radiator 24 with simple dependence of the phase of the azimuthal and the radiation diagram of the ring line radiator.
  • the directional antenna can be easily formed with a directional pattern with azimuthal main direction.
  • crossed emitters 24 are, as already stated, for example DE-A-4008505 and DE-A-10163793 known.
  • the from the DE-A-4008505 known antenna is constructed on a substantially horizontally oriented conductive surface and consists of crossed horizontal dipoles, which are mechanically fixed at an azimuthal angle of 90 degrees to each other and attached to the upper end of a fixed to the conductive base linear vertical conductor.
  • the from the DE-A-10163793 known antenna is also constructed on a generally horizontally oriented conductive base and consists of crossed azimuthally mounted at 90 ° to each other frame structures.
  • the mutually spatially offset by 90 ° antenna parts in the electrical phase are interconnected shifted by 90 ° to each other to generate the circular polarization.
  • the effect of all these crossed emitters is essentially based on the fact that the individual antenna parts are placed at a right angle "crossed" and perpendicular to the ground plane levels and offset the antenna parts of the different planes to produce the circular polarization by 90 ° in phase are interconnected.
  • the effect of patch antennas can also be represented in a similar way.
  • a ring line emitter 2 according to the invention has the particular advantage that it can be provided as a basic form for a single antenna system, which by additional placement with a crossed emitter - such as from DE-A-10163793 , of the DE-A-4008505 or as a readily available patch antenna - can be supplemented to a directional antenna that can be tracked in the main direction of the radiation or to an antenna diversity system.
  • a crossed emitter - such as from DE-A-10163793 , of the DE-A-4008505 or as a readily available patch antenna - can be supplemented to a directional antenna that can be tracked in the main direction of the radiation or to an antenna diversity system.
  • the ring line emitter 2 is designed to extend in a horizontal plane with the height h over the conductive base 6, so that it forms an electrical line with respect to the conductive base 6 with a characteristic impedance resulting from the height h and the effective diameter of the im Essentially results in a wire-shaped loop conductor.
  • a support of vertical components of the electric radiation field is carried out according to the invention by vertical radiators 4, which allow the emission of vertical electric field components, and on the excitation 3 of the ring line radiator 2 takes place in the example shown.
