Definitions

  • the invention relates to a phase-controlled antenna with a multiplicity of active antenna modules arranged at a certain mutual distance, each with a transmitting / receiving module (S / E module) and at least one radiating element.
  • phase-controlled antennas phased array
  • Such phase-controlled antennas are already generally known and are mainly used in radar technology (NTZ Vol. 39, 1986, H.9, pages 630-635).
  • a phase-controlled antenna consists of a large number of identical radiator elements, which are arranged on a mostly flat surface of a certain geometric shape in equidistant rows and columns.
  • the electronic swiveling of the directional diagram of the antenna is generally carried out by electronically changeable phase shifters which are switched into the feed line of each radiating element. This makes it possible to swivel the antenna beam quickly and without mechanical movement of the antenna.
  • such antennas can also radiate very high power. However, sufficient dissipation of the heat loss occurring must be ensured.
  • phased array antennas it is customary (loc. Cit.
  • the invention is therefore based on the object, in particular in the case of a phase-controlled antenna of the type mentioned, with the most compact possible and optimal arrangement of the associated assemblies with regard to the routing of the associated assemblies, to significantly improve the cooling of the S / E modules compared to previously known solutions.
  • each S / E module is fastened at its radiator end to a common mounting plate lying behind the radiator elements, as seen in the receiving direction, and in that the mounting plate is designed with cooling channels for a cooling liquid over its entire surface is.
  • the mounting plate is arranged between the radiator elements and the S / E modules, the S / E modules being fastened to the mounting side with their radiator-side end face and the mounting plate having transverse openings for fastening and the HF Connection of the radiator elements to the S / E modules is formed. So that the mounting plate is designed so that it allows the passage of the radiator element belonging to each S / E module and allows the attachment of a sufficient number of cooling channels.
  • an antenna according to the invention is constructed in such a way that the mounting plate is formed with recesses for pushing through the S / E modules in such a way that it has a honeycomb structure in such a way that the S / E modules are provided with an attachment at their radiator end are, the side facing away from the radiator end of the S / E modules after inserting an S / E module through a recess in the mounting plate, a fastening and contact surface for fastening an S / E module to the mounting plate or for heat transfer from the S / E module to the mounting plate, and that the radiator elements are attached and connected directly to the free, radiator-side end of the S / E modules.
  • the mounting plate is therefore not arranged between the radiator elements and the S / E modules, but is provided with recesses through which the S / E modules can be inserted from the front of the antenna through the mounting plate.
  • the emitter elements are not inserted through the mounting plate, but are attached directly to the S / E module.
  • each S / E module for heat transport within the module and for the mounting plate is designed with a base plate of appropriate thickness in order to keep the temperature difference along the S / E module small.
  • FIGS. 1 and 2 shows a number of active antenna modules for a phase-controlled antenna arranged at a certain mutual distance (raster), the antenna modules each having a transmit / receive module (S / E module) 4 with at least one radiator element 1 exhibit. Dipoles, open waveguides and stripline radiators are primarily used for the individually fed radiator elements.
  • the antenna module which previously contained a radiator element and a phase shifter, now also includes, in a known manner, part of the transmitter and / or receiver as an S / E module, so that the antenna module becomes the active module.
  • the S / E modules also generate heat loss.
  • Each of the S / E modules 4 is therefore attached at its radiator end to a common mounting plate 3, which is also designed as a cooling plate and is located behind the radiating elements 1 in the receiving direction and thereby becomes a cooling plate in that it has cooling channels over its entire surface 7 is designed for a cooling liquid.
  • the mounting plate 3 is arranged between the radiator elements 1 and the S / E modules 4.
  • the mounting plate 3 has transverse openings for the attachment and the HF connection of the radiator elements trained on the S / E modules.
  • the radiator elements 1 are therefore shown in FIG.
  • the S / E modules 4 are connected to a removable column distributor 9 via an RF connector 6 and a guide pin 8.
  • the S / E modules 4 can be removed from the mounting plate after removing this column distributor 9 and loosening the fastening screw 2, ie can be pulled out from the rear of the antenna or from the distributor side.
  • FIG. 1 for the lowermost of the S / E modules 4, these are designed for heat transport within the module and for the mounting plate with a base plate 10 of appropriate thickness in order to minimize the temperature difference along the S / E module hold.
  • the mounting plate 3a is not arranged between the radiator elements 1 and the S / E modules 4a, but is only provided in the region of the radiator end of the S / E modules In addition to the cooling channels 7, they are also provided with recesses 11 through which the S / E modules 4a can be inserted from the front of the antenna through the mounting plate 3a.
  • the S / E modules 4a are provided at their radiator end with a shoulder 12, the side facing away from the radiator end has a fastening and contact surface for fastening an S / E module 4a to the mounting plate 3a or for the heat transfer from S / E module forms on the mounting plate.
  • the radiator elements 1 are here directly on the free Front end of the S / E modules 4a fixed on the radiator or plugged onto the S / E module by means of an HF plug 5.
  • the mounting plate 3a (Fig.5) consists of two essentially identical and e.g. halves which can be connected to one another by soldering and are each formed on the mutually facing surfaces with a meandering cooling channel 7a or 7b.
  • the cooling duct then formed by the two adjoining halves of the mounting plate 3a is - as shown in FIG. 5 - divided into two separate cooling ducts 7a and 7b by an inserted strip 13.
  • the inlet and outlet of the separate cooling channels 7a and 7b are each arranged in such a way that the coolant flows countercurrently in the two halves of the mounting plate 3a.
  • the recesses 11 of the mounting plate 3a for pushing through the S / E modules 4a are arranged between the individual meandering loops of the cooling channel 7a or 7b and are designed here as openings one behind the other, rectangular in cross section (FIGS. 4 and 6).
  • the mounting plate 3a is not yet shown with threaded holes for the mounting screws 2a.
  • FIGS. 4 to 6 The construction of a mounting plate shown in FIGS. 4 to 6 can in principle also be used for the solution proposed in FIG. However, the rectangular openings 11 are then omitted and the holes for the fastening screws 2 take their place.
