Horizontal omnidirectional high-gain vertical polarization array dipole antenna

Abstract

The invention discloses a horizontal omnidirectional high-gain vertical polarization array dipole antenna, which comprises a PCB, N pairs of dipole array oscillators, microstrip transmission lines, micro-short width lines and reverse longitudinal width lines, a feed coaxial line, a connector, external sleeves, crimping sheets and bolts, wherein the micro-short width lines and the reverse longitudinal width lines are coupled to a reverse first-stage dipole array oscillator to form a micro-short coupling balun converter and a longitudinal coupling balun converter, and have a phase compensation function of exiting oscillator current; one end of the 50ohm feed coaxial line is electrically connected with the antenna through the crimping sheets in a welding manner and the other end is electrically connected with the connector. A balun transformation, impedance transformation, phase difference compensation and secondary coupling excitation integration technology is used for the first time, and the international technical difficulties of the horizontal omnidirectional high-gain elongated planar printed array antenna are overcome. By a crimping technology of the feed coaxial line, the coupling degree of each antenna oscillator is improved, the consistency and the stability of the antenna are strengthened and the service life of the antenna is prolonged. The horizontal omnidirectional high-gain vertical polarization array dipole antenna is simple in structure, simple in production, moderate in cost and convenient to use.
