Definitions

  • the present invention relates to a compact radiating element with low losses. It applies in particular to the field of active antennas transmitting / receiving radio frequency signals.
  • Active antennas generally consist of a network of radiating elements connected to passive and active microwave components, such as filters, amplifiers, phase shifters, and a beamforming network that combines the electromagnetic signals emitted by each radiating element.
  • passive and active microwave components such as filters, amplifiers, phase shifters, and a beamforming network that combines the electromagnetic signals emitted by each radiating element.
  • the connections between radiating elements and active equipment must be as short as possible in order to reduce transmission losses.
  • the electromagnetic signal processing means must be placed as close as possible to the emission source and the transmitting and receiving means must be located in the mesh of the network.
  • the supply of the radiating elements is most often carried out by electromagnetic coupling of the resonant structure to the supply line which is parallel to the radiating mass plane and produced in so-called planar technology.
  • the feed line can be, for example, micro-ribbon, coplanar or stripline type (stripline) and it can be coupled to the resonant structure either by proximity coupling or by electromagnetic coupling through a coupling slot made in the radiant ground plane.
  • the power supply circuit being placed on the radiating ground plane or under it, the resonant structure can be disturbed by unwanted radiation or parasitic couplings.
  • the supply circuit being placed parallel to the plane radiant mass, it is difficult to insert into the mesh network active equipment. This difficulty is further reinforced when the network operates in orthogonal polarizations, since it is then necessary to double certain equipment (especially active ones). It is therefore the insertion constraints that impose the minimum sizes of the meshs of the networks.
  • the planar technology with excitation parallel to the radiating mass plane is therefore handicapped by the need to produce multilayer circuits on which microwave circuits such as filtering circuits, redundancy switches, low noise amplifiers, etc. are reported. ... It requires connections between good quality layers for microwave signals, which is complex to achieve.
  • the document EP 1 605 546 discloses examples of compact radiating elements having an orthogonal supply line and a coupling aperture for transferring electromagnetic energy from the orthogonal line to a dielectric resonator.
