Definitions

  • the invention relates to an antenna, in particular mobile radio antenna, according to claims 1-4.
  • Mobile radio antennas for mobile radio base stations are usually constructed so that a plurality of radiator arrangements are provided in front of a reflector plane in the vertical direction one above the other.
  • these radiator arrangements can consist of a multiplicity of dipole radiators, for example also in the form of crossed dipoles, in the form of a dipole square, etc., that is to say in the form of radiator types having a dipole structure.
  • antennas are known as so-called patch radiators.
  • GSM 900 network of the 900 MHz frequency range for example, for the so-called GSM 1,800 network of the 1,800 MHz range or for example also the 1,900 MHz frequency range, as is customary in the USA and used in a large number of other states.
  • GSM 1,800 network of the 1,800 MHz range for example also the 1,900 MHz frequency range, as is customary in the USA and used in a large number of other states.
  • the UMTS network has a frequency range around 2,000 MHz.
  • Such mobile radio antennas at least as dual-band antennas, whereby triple-band antennas (for example for the 900 for the 1,800 and the 1,900 or for example the 2,000 MHz band) are also suitable.
  • the antennas are preferably designed as dual-polarized antennas for operation with a polarization of + 45 ° and -45 °. It is also customary to protect such antennas by a plastic hood against the weather. However, this so-called radome has mainly to perform mechanical tasks and envelops all the radiant antenna parts equally.
  • Such an antenna for operation in at least two mutually offset frequency bands has become known for example from DE 198 23 749 A1.
  • a dual-band antenna array is known from WO 99/59233 A.
  • This antenna array comprises patch antenna elements, above which dipole radiators are arranged in the form of cross dipoles.
  • the cross dipoles are arranged above a conductive plate, which serves as a parasitic element for the patch antenna and as a reflector for the cross dipoles.
  • the mentioned dielectric body in plan view be designed n-polygonal. It may, for example, extend above a dipole radiator arrangement, for example in the form of a crossed dipole, for example using crossed dipoles, dipole squares or using patch radiators.
  • the dielectric body according to the invention which is also referred to below as a dielectric tuning plate in plan view, be designed symmetrically in plan view, in particular at least have sections which are formed and arranged symmetrically with respect to a single radiator arrangement.
  • the dielectric bodies according to the invention can be made of suitable plastic material, for example Polystyrene, fiberglass (GRP) etc. exist.
  • suitable plastic material for example Polystyrene, fiberglass (GRP) etc. exist.
  • a material is used for the dielectric body whose dielectric does not have a high dissipation factor.
  • the invention has a particularly favorable effect, for example, in the frequency range from 800 to 1000 MHz and from 1700 to 2200 MHz.
  • the dielectric body is designed plate-shaped and extends in a parallel plane in front of the reflector.
  • it may be provided with existing of the same material fasteners or feet (generally spacers, etc.) to arrange it in a predetermined, considered favorable for distance in front of the reflector sheet.
  • the extension height is lower than ⁇ / 2.
  • the mobile radio antennas are set to have a half width of 65 °.
  • this 65 ° half-width can usually not be set completely identically for the at least two frequency bands, especially if they are very broadband. Therefore, a deviation with respect to the at least two provided frequency bands of, for example, 65 ° ⁇ 10 ° (or at least ⁇ 7 °) is common in the prior art. According to the invention, this deviation can now be improved to 65 ° ⁇ 5 ° (or even only ⁇ 4 ° and less).
  • the antennas are often adjusted so that they radiate each in a horizontal 120 'sector angle. This is also called sector. As a result, three sectors are formed per antenna mast. In the sector boundaries, therefore, a corresponding mobile radio antenna radiates at an angle of + 60 ° or -60 °, the suppression of the cross-polar component, in particular at the sector boundaries according to the prior art, especially in broadband antennas having poor values.
  • a ratio of 10 dB or even better with respect to the suppression of the cross-polar component can be realized here even in the sector boundaries at ⁇ 60 °.
  • the decoupling can likewise be significantly improved in this case.
  • the required decoupling has a magnitude of more than 30 dB. This is a very big problem, especially with broadband antennas or antennas with electrically adjustable lowering. In the case of the antenna according to the invention, this value is significantly exceeded, especially when the antennas are broadband and additionally electrically adjustable.
  • the antenna 1 comprises five individual radiators, namely two first radiators 4a offset in the vertical direction for a first lower frequency range and three vertically offset second radiators 4b for a higher frequency range.
  • the first radiators 4a are dipole radiators 7, which are arranged in the manner of a dipole square 13 and held by so-called symmetries 7 ', which run at least partially to their common center, and are fastened to an electrically conductive reflector 11.
  • the second radiators 4b arranged within these first radiators 4a are formed in the manner of a crossed dipole 15 with two dipoles perpendicular to one another.

  • the mentioned radiators are arranged in front of the vertically oriented reflector 11, wherein the reflector 11 may be formed, for example, from a reflector plate 11 ', with two edge sections 12' set up at its vertical sides 12 from the reflector plane in the emission direction.
  • a dielectric body 21 is furthermore provided which, in the exemplary embodiment shown, is plate-shaped and extends at least substantially parallel to the reflector plane. It is preferably located at a distance in front of the reflector plane that is smaller than ⁇ / 2 of the highest transmitted frequency range or smaller than ⁇ / 2 of the associated center frequency of the highest frequency range.

  • the non-protective dielectric body is provided so as to extend in parallel at least partially above parts of the radiator assembly at a distance in front of the reflector 11.
  • the dielectric body 21 extending parallel to the reflector 11 can have an areal dimension which is greater than the planar extension dimension of possible spacers, feet or other elements belonging to the dielectric body 21 that is parallel to the plane of the reflector 11 or with this connected or the reflector 11 extending fasteners.
  • the dielectric body is arranged completely or at least with a section at a distance in front of the reflector 11, and above the radiator arrangement provided for the upper frequency range. It also proves to be advantageous if the dielectric body is located entirely or at least with a section below the radiator arrangement provided for the lower frequency range. Both of the aforementioned conditions should preferably be fulfilled simultaneously, the effect being particularly favorable when the dielectric body 21 is thus located entirely or with at least one section above the radiator arrangement provided for the upper frequency range and at the same time below the radiator arrangement provided for the lower frequency range and extends completely or substantially parallel to the reflector.
  • the effect is particularly advantageous when the dielectric body 21 is related to its total volume and / or Total weight is at least sufficiently in this position, ie, for example, with more than at least 30%, 40%, 50% or especially more than 60%, 70%, 80% or 90% of its total weight and / or volume specified area is located.
  • the at least one dielectric body 21 in the projection perpendicular to the reflector 11 located therebelow is smaller than the reflector sheet.
  • the dielectric body may also have a size that ultimately corresponds to the size of the reflector 11.
  • the dielectric body 21 is arranged with a first portion symmetrically within the first radiator 4a and thus above the second radiator 4b therein, in the embodiment shown - since the first radiator 4a are formed from a dipole square - in a square shape.
  • the dielectric body 21 formed in this way is provided in the exemplary embodiment shown with a central vertical section 21b which connects the sections 21a in the region of the dipole squares 13 of the two first radiator arrangements 4a offset in the illustrated embodiment.
  • the dielectric tuning plate 21 thus formed is designed in one piece.
  • it could also consist of several parts which correspond at least approximately to the reproduced in Figure 1 form, so for example, comprise two sections 21a, which are square and arranged according to the dipole square 13 each concentric with this parallel to the reflector plane. Between these two sections 21a, the longer connecting section 21b could then be provided running.
  • the half-width, the value for the suppression of the cross-polar component, the decoupling, as well as the bandwidth increase can be improved in an advantageous manner.
  • Adverse influences for the lower frequency range or the low frequency bands are virtually undetectable.
  • the dielectric body is preferably mechanically attached to the radiators, for example at their symmetries.
  • the embodiment according to FIGS. 4 to 6 differs from that according to FIGS. 1 to 3 in that patch emitters 27 are used for the second emitters 4b (instead of the cross emitters 15), ie surface emitters, for example in the form of a square emitter element, which have a suitable spacing height in front of the reflector 11 are aligned centrally and symmetrically with the same polarization orientation to the first radiators 4a.
  • patch emitters 27 are used for the second emitters 4b (instead of the cross emitters 15), ie surface emitters, for example in the form of a square emitter element, which have a suitable spacing height in front of the reflector 11 are aligned centrally and symmetrically with the same polarization orientation to the first radiators 4a.

It may also consist of several separate separate sections, which are then joined together to a desired shape quasi, it is harmless if the individual elements from which the dielectric body 21 may be formed in the mounting direction not together over the entire surface, but for example in one schematic top view of Figure 7 between the individual elements gap gaps 31 remain.
  • the dielectric tuning element or body may also be provided with spacers for attachment to the reflector 21, wherein the spacers 41 may be separate spacers or of the same material can exist, as the dielectric body 21 itself.
