Definitions

  • Embodiments of the present disclosure relate to, but not limited to, the technical field of communication, and in particular to, but not limited to, a half-wave dipole, a half-wave dipole assembly, and an antenna.
  • an antenna that uses a half-wave dipole as a radiation module is usually used for communication.
  • MIMO Multi Input Multi Output
  • each cell or sector is required to be configured with multiple antennas, and these antennas are required to have zero coherence.
  • Orthogonally polarized antennas which meet these requirements can be used for communication in such a system.
  • two half-wave dipoles are placed vertically on a plane, so as to realize the orthogonal polarization characteristics of two antennas.
  • the half-wave dipole has the advantages of simple engineering implementation and space saving.
  • the existing technology because the operating bandwidth of the half-wave dipole is too narrow, multiple independent half-wave dipoles and feeder systems are required in order to achieve multi-band coverage, which overburdens mobile base station antenna towers which are already quite crowded.
  • building a new mobile base station antenna tower not only requires huge investment, but is also confronted with difficulty in land acquisition.
  • a half-wave dipole, a half-wave dipole assembly, and an antenna provided by the present disclosure mainly solve, to at least a certain extent, the technical problem of high costs required for achieving multi-band coverage due to the narrow operating bandwidth of the half-wave dipole.
  • the present disclosure provides a half-wave dipole, including: a first radiation arm and a second radiation arm.
  • the first radiation arm and the second radiation arm each include two radiators arranged along a straight line and a connector arranged between the radiators.
  • the connector is configured for disconnecting or connecting the two radiators in respective radiation arms.
  • the radiator close to the other radiation arm is configured for connecting to a feeding unit.
  • the radiators of the first radiation arm and the radiators of the second radiation arm are symmetrically arranged.
  • a half-wave dipole assembly which includes at least one half-wave dipole described above.
  • an antenna which includes at least one half-wave dipole described above.
  • An antenna includes a radiation unit and a feeding unit.
  • a half-wave dipole is used as the radiation unit.
  • the half-wave dipole includes two symmetrically arranged radiators, and has the advantages of simple engineering implementation and space saving.
  • the operating bandwidth of the half-wave dipole cannot be too wide. If the operating bandwidth of the half-wave dipole is too wide, the standing wave, beam width, gain, etc., of the antenna may deviate from design values. Therefore, in the existing technology, the bandwidth of the half-wave dipole is relatively narrow, and high costs are incurred when achieving multi-band coverage.
  • the half-wave dipole includes a first radiation arm 10 and a second radiation arm 20.
  • the first radiation arm 10 and the second radiation arm 20 each include two radiators arranged along a straight line and a connector arranged between the radiators.
  • the connector is configured for disconnecting or connecting the two radiators in respective radiation arms.
  • the radiator close to the other radiation arm is configured for connecting to a feeding unit 30.

  • the second radiator 102 and the third radiator 201 are symmetrically arranged (that is, the second radiator 102 and the third radiator 201 are identical, and the positions of the second radiator 102 and the third radiator 201 are symmetrical).
  • the second radiator 102 in the first radiation arm 10 is close to the second radiation arm 20.
  • the third radiator 201 in the second radiation arm 20 is close to the first radiation arm 10.
  • the second radiator 102 and the third radiator 201 are configured to connect to the feeding unit 30.

  • the first radiator 101 when the first radiator 101 is connected to the second radiator 102 by the first connector 103, the first radiator 101 is connected to the feeding unit 30 through the second radiator 102, so that both the first radiator 101 and the second radiator 102 are effective radiators of the first radiation arm 10, and in this case the first radiation arm 10 operates in a first band (it should be understood that the first band corresponds to a total length of the first radiator 101 and the second radiator 102).
  • the first radiator 101 When the first radiator 101 is disconnected from the second radiator 102 by the first connector 103, only the second radiator 102 is connected to the feeding unit 30, so that the effective radiator of the first radiation arm 10 is the second radiator 102, and the first radiation arm 10 operates in a second band (it should be understood that the operating band corresponds to a length of the second radiator 102).

  • the radiator may be a metal radiator, and the metal radiator may be a printed dipole or a die-cast dipole.
