Problems solved by technology

Generally, the gain of a single dual-polarized antenna oscillator is about 8dBi. If a gain of 10dBi is to be achieved, two oscillators are required to form an array. This not only has a complex structure, but also requires a relatively large size, which cannot meet the needs of increasingly miniaturized base stations. Antenna Requirements

Embodiment 1

[0034] The dual-polarized antenna vibrator provided by the present invention includes: a metal reflector 1, the metal reflector 1 is square; a dual-polarized radiation plate 2 is arranged above the metal reflector 1; a leading radiation plate 3 is arranged on the dipole above the radiating plate 2; the radiating plate 3 is provided with a radiating sheet 4. Among them, the dual-polarized radiating plate 2 includes a +45° polarized feed network, a -45° polarized feed network, a first folded dipole 204, and a second folded dipole 205; +45° polarized feed The network includes a +45° polarized feeding port 201 and a first power dividing network, and the -45° polarized feeding network includes a -45° polarized feeding port 202 and a second power dividing network. The +45° polarized feeding port 201 is set on the first power dividing network, and the -45° polarized feeding port 202 is set on the second power dividing network. The +45° polarized feed port 201 is connected to two fir...

Embodiment 2

[0045] The present invention also provides an antenna unit including the dual-polarized antenna element described in Embodiment 1 above, the antenna unit can work between 2.3G-2.8GHz frequencies, and is suitable for 4G / 5G base stations, WiFi and other mobile communications on the device. The standing wave of the antenna can reach 1.4, the isolation can reach 30dB, the lobe width in the horizontal and vertical directions can reach 50°, and the gain of the antenna can reach 10.5dBi, achieving a high Gain, to solve the problem that when the antenna requires high gain and small size, the isolation between dual polarizations deteriorates due to too close to the array distance; when the antenna requires high gain, the horizontal and vertical lobes are narrowed at the same time, because Simultaneous horizontal and vertical arrays lead to complex antenna structures and feed networks, high cost, and poor consistency, which meets the antenna requirements of increasingly miniaturized bas...

Abstract

The invention discloses a dual-polarized antenna oscillator and an antenna comprising the antenna oscillator. The dual-polarized antenna oscillator adopts a three-layer combination of a metal reflector, a dual-polarized radiation The poles are arranged in a diagonal array. On the one hand, the isolation between the +45° polarized feed port and the -45° polarized feed port is improved, and on the other hand, the gain of the antenna is maximized, so that a single antenna The gain of the vibrator reaches 10.5dBi, which not only simplifies the structure of the antenna, but also reduces the size of the antenna.

Description

technical field [0001] The invention belongs to the field of antenna design, and in particular relates to a dual-polarization antenna oscillator and an antenna including the antenna oscillator. Background technique [0002] With the development of the communication industry, base stations tend to be miniaturized, and base station antennas need to meet the gain requirements in smaller and smaller spaces. Generally, the gain of a single dual-polarized antenna oscillator is about 8dBi. If a gain of 10dBi is to be achieved, two oscillators are required to form an array. This not only has a complex structure, but also requires a relatively large size, which cannot meet the needs of increasingly miniaturized base stations. Antenna needs. Contents of the invention [0003] The object of the present invention is to provide a dual-polarization antenna element and an antenna including the antenna element, so that the gain of a single antenna element can reach 10.5dBi, which not onl...
