Abstract

The invention discloses a four-polarization radiation oscillator and a four-polarization antenna and relates to the technical field of communication antennas. The four-polarization radiator oscillator with perpendicularly arranged symmetrical dipoles combined with horizontally arranged dipoles is designed, four radiation elements which are in horizontal and perpendicular dual polarization and +/-45-degree dual polarization respectively form the four-polarization radiation oscillator, the phase centers of the four polarization radiation elements are the same, feed is performed in different polarization modes separately, the horizontal polarization radiation element and the perpendicular polarization radiation element are mutually orthogonal and both arranged perpendicular to a reflection board, the +/-45-degree polarization radiation elements are also mutually orthogonal and arranged parallel with the reflection board, the horizontal and perpendicular dual polarization radiation elements and the +/-45-degree dual polarization radiation elements are distributed at intervals of 45 degrees, the distance from each of the four polarization radiation elements to the reflection board is lambda/4, four feed points are reasonably kept away, four feeder lines are inserted in a staggered mode, and thus the four-polarization radiation oscillator which is highly integrated and compact in structure is obtained.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to a four-polarization radiation oscillator and a four-polarization antenna. Background technique [0002] At present, the basic radiating elements of mobile communication base station antennas include single-polarized radiating elements, such as horizontally polarized radiating elements, vertically polarized radiating elements, or dual-polarized radiating elements, such as horizontal and vertical dual-polarized radiating elements, ±45° Dual-polarized radiating elements, etc., these radiating elements form a single-polarized or dual-polarized multi-antenna array after being arrayed. [0003] A multi-antenna array composed of one polarization (such as single polarization) or two polarizations (such as dual polarization) radiating elements, due to the limitation of antenna feed space, or due to antenna gain, horizontal beam width, vertical plane Due to the constraints ...
