The invention discloses a multi-resonance-point vertically polarized magnetic current end-on-fire antenna. The multi-resonance-point vertically polarized magnetic current end-on-fire antenna comprisesa non-ground coplanar waveguide, metal short-circuit columns, a dielectric substrate and a magnetic current unit group; the non-ground coplanar waveguide is arranged at the bottom of the dielectric substrate, and the magnetic current unit group is in contact with a conduction band of the non-ground coplanar waveguide through the four metal short-circuit columns; the non-ground coplanar waveguidecomprises a metal plate and the conduction band, wherein the metal plate and the conduction band are in the same plane, and the tail end of the conduction band is disconnected from the metal plate; the magnetic current unit group includes four magnetic current units, and the resonant frequencies of the four magnetic current units are 5.6 GHz, 6 GHz, 6.3 GHz and 6.5 GHz correspondingly; and the magnetic current units comprise first short-circuit metal sheets, second short-circuit metal sheets and rectangular patches, and the first short-circuit metal sheets and the second short-circuit metal sheets are correspondingly arranged at the two ends of one sides of the rectangular patches. The problems that the vertical polarization, less resonance points and narrow bandwidth cannot be realized when the antenna is horizontally placed in the prior art are solved.

Description

technical field [0001] The invention relates to the field of antennas, in particular to multi-resonance point vertically polarized magnetic current end-fire antennas. Background technique [0002] As the part of transmitting and receiving electromagnetic waves in the communication system, the performance of the antenna plays an important role in the performance of the overall system. In modern communication, the vertically polarized antenna has less attenuation along the ground plane, and with its vertical polarization characteristics, the transceiver device can receive it in any direction. Therefore, vertically polarized antennas are often used in ground wave communication systems. End-fire antennas have the characteristics of high gain and excellent directivity, and are often used in automotive, television, radar and other fields. [0003] When the end-fire antenna is placed parallel to the ground, it is difficult to achieve vertical polarization. Most of the antennas ar...
