Embodiment Construction

[0015] Various embodiments of the broadband dual-polarized antenna of the present invention will be described in detail below.

[0016] like figure 1 As shown, it is a schematic structural diagram of Embodiment 1 of the broadband dual-polarized antenna of the present invention, including: a radiation plate 120 (since the radiation plate is below the dielectric plate, so figure 1 The specific structure is not shown in ), dielectric plate 130, feeder plate 140, director 150, the radiation plate includes orthogonal +45° polarizers and -45° polarizers, each polarizer includes two The radiating board, the feeding board includes a first sub-feeding board and a second sub-feeding board. Here, the orthogonal +45° polarizer and -45° polarizer mean that the +45° polarizer and the -45° polarizer have a cross-shaped structure, that is, the symmetry lines of adjacent sub-radiation plates are perpendicular to each other. Wherein, the figure of each radiating plate may be a figure symmetri...

Abstract

A broadband dual-polarized antenna comprises a feeding panel, a dielectric panel, a radiant panel and a director, wherein the radiant panel comprises a +45-degree polarization oscillator and a -45-degree polarization oscillator which is orthogonal to the +45-degree polarization oscillator, and each polarization oscillator comprises two radiant sub-panels; the feeding panel comprises a first feeding sub-panel and a second feeding sub-panel, the dielectric panel is supported on a reflecting panel through coaxial feeders, the feeding panel and the radiant panel are printed on the upper layer and the lower layer of the dielectric panel, the feeding sub-panels of the feeding panel are connected with inner conductors of the coaxial feeders respectively, the first feeding sub-panel is aligned to one radiant sub-panel of the +45-degree polarization oscillator so as to conduct coupled feeding, the second feeding sub-panel is aligned to one radiant sub-panel of the -45-degree polarization oscillator so as to conduct coupled feeding, and outer conductors of the coaxial feeders are connected with the other two radiant sub-panels respectively so as to conduct feeding; the director is arranged above the feeding panel, the feeding panel is used for controlling a high-frequency resonance point, the radiant panel is used for controlling a low-frequency resonance point, and the director is used for controlling a high frequency radiation pattern. The broadband dual-polarized antenna improves broadband matching performance.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband dual-polarization antenna. Background technique [0002] With the rapid development of mobile communication systems, people's requirements for mobile communication are getting higher and higher, and the number of mobile communication equipment is greatly increased, such as the number of base station antennas, which increases the installation and maintenance of equipment. Increased the operating costs of major operators. At the same time 2G, 3G, LTE and the upcoming 4G, the working frequency coverage is required to cover GSM1710 / 1800 / UMTS / LTE2300 / 2500 (1710~2690MHz). [0003] In order to meet the needs of current wireless communication development, various structures of broadband dual-polarization base station antenna units have been studied. At the same time, not only put forward new requirements for the impedance bandwidth, pattern stability, gain stability, and i...
