Definitions

  • the present invention relates to the communications field, and in particular, to a radio transceiver apparatus, an antenna element, and a base station.
  • a radio transceiver apparatus is a common signal transceiver structure, mainly including structures such as an antenna element, a dielectric substrate, a shielding cover, and a metal carrier.
  • the antenna element configured in the radio transceiver apparatus is usually an omnidirectional antenna element.
  • the omnidirectional antenna element is manifested as 360° uniform radiation in a horizontal directivity pattern, commonly referred to as "non-directional", and is manifested as a beam of a specific width in a vertical directivity pattern.
  • the omnidirectional antenna element is usually disposed in a central location of a metal carrier (the metal carrier is equivalent to a reference ground).
  • the omnidirectional antenna element is centrosymmetrically disposed on a shielding cover of the radio transceiver apparatus, and a radiation patch or a radiator of the antenna element is designed to be a centrosymmetric (also referred to as rotational symmetric) structure.
  • the antenna element in the symmetric structure needs to be disposed in the center of the metal carrier. Structure symmetry is used to ensure that the antenna element has a feature of uniform radiation on a cross section parallel to the shielding cover, thereby achieving high roundness performance.
  • embodiments of the present invention provide a radio transceiver apparatus, an antenna element, and a base station.
  • the invention is set out in the appended set of claims.
  • both the feeding structure and the radiation patch in each of the at least one antenna element disposed at the edge of the metal carrier are non-centrosymmetric structures
  • the metal carrier is used as a reference ground of the antenna element
  • the metal carrier is also non-centrosymmetric relative to each antenna element.
  • distribution of ground currents generated by the non-centrosymmetric radiation patch and the non-centrosymmetric reference ground may form relative centrosymmetry.
  • the antenna element in the radio transceiver apparatus Compared with an omnidirectional antenna element in a conventional radio transceiver apparatus, the antenna element in the radio transceiver apparatus provided in the embodiments of the present invention has a better antenna pattern roundness within a broadband range. Therefore, an antenna pattern roundness is effectively improved.
  • FIG 1 shows a commonly used omnidirectional antenna element 10 provided in a related technology.
  • the omnidirectional antenna element may be referred to as a broadband monopole antenna element.
  • the omnidirectional antenna element 10 includes: a radiation patch 11, a short-circuit probe 12 with one end connected to the radiation patch 11 and the other end grounded, and a feeding probe 13, where one end of the feeding probe 13 is grounded, a slot H is formed between the radiation patch 11 and the other end of the feeding probe 13, feeding is performed between the radiation patch 11 and the feeding probe 13 by using the slot H, and a feed point is a point A.
  • FIG 2 is a schematic structural diagram of a conventional radio transceiver apparatus 20.
  • the radio transceiver apparatus 20 includes at least one omnidirectional antenna element 10, a carrier dielectric substrate (also referred to as a radiation board) 201, a shielding cover 202, and a metal carrier 203.
  • the metal carrier 203 is a housing, the carrier dielectric substrate 201 is disposed in the metal carrier 203, the shielding cover 202 is fastened on the metal carrier, and the omnidirectional antenna element 10 is formed on the shielding cover 202 or the metal carrier 203.
  • the omnidirectional antenna element 10 is formed on the shielding cover 202 for description. It can be seen from FIG 2 that the omnidirectional antenna element 10 is a three-dimensional structure obtained by separate processing. After the processing, the omnidirectional antenna element 10 is disposed on the shielding cover 202 or the metal carrier 203.
  • symmetry related to a roundness in three aspects symmetry of an antenna element body, symmetry of an installation location, and symmetry of a metal carrier. If symmetry in all the three aspects is achieved, to be specific, a centrosymmetric (also referred to as rotational symmetric) omnidirectional antenna element is centrosymmetrically disposed on a centrosymmetric metal carrier, the roundness of the radio transceiver apparatus is usually relatively good. However, if symmetry in one of the three aspects is broken, the roundness usually deteriorates.
  • the metal carrier is a centrosymmetric structure, for example, a square structure or a round structure, and the shielding cover fastened on the metal carrier is also a centrosymmetric structure.
  • the metal carrier may be a centrosymmetric prism-shaped structure.
  • an edge of the metal carrier may have a fillet or a beveling.
  • the omnidirectional antenna element is usually disposed in a central location of the metal carrier.
  • the omnidirectional antenna element is centrosymmetrically disposed on the shielding cover of the radio transceiver apparatus, and a radiation patch or a radiator of the antenna element is designed to be a centrosymmetric structure.
  • the antenna element in the symmetric structure needs to be disposed in the center of a reference ground (for example, a ground marked in FIG 3 ). Structure symmetry is used to ensure that the antenna element has a feature of uniform radiation on a cross section parallel to the reference ground, thereby achieving high roundness performance.
  • FIG 3 shows a schematic diagram of corresponding current distribution.
  • a ground current of the antenna element is distributed centrosymmetrically.
  • the antenna element is not disposed in the central location of the metal carrier, symmetry of the antenna element relative to the metal carrier cannot be ensured.
  • An inevitable consequence is that the ground current is distributed non-centrosymmetrically, and an antenna pattern roundness of the antenna element deteriorates.
  • At least two omnidirectional antenna elements usually need to be installed in the radio transceiver apparatus.
  • an antenna element not disposed in the central location of the metal carrier exists inevitably. Symmetry of each antenna element relative to the reference ground cannot be ensured, and therefore the antenna pattern roundness of the conventional radio transceiver apparatus having a plurality of antenna elements is relatively poor.
  • FIG 4 is a schematic diagram of current distribution of an antenna element in a scenario that is shown in FIG 2 and in which an omnidirectional antenna element is disposed on each of four corners of the shielding cover.
  • the metal carrier is used as the reference ground of the antenna element (for example, a ground marked in FIG 4 ), and is not centrosymmetric relative to each antenna element. A ground current of each antenna element is therefore non-centrosymmetrically distributed.

  • Antenna pattern roundnesses corresponding to different bandwidths in FIG 5 are shown in Table 1.
  • a cross section of a three-dimensional radiation pattern at an angle Theta in a horizontal plane direction is obtained.
  • a value range of Theta is usually from 0° to 180°.
