Embodiment 1

[0028] see Figure 1 to Figure 4 , the broadband low-profile dual-polarized omnidirectional antenna of the present invention comprises: the first dielectric plate 1 and the second dielectric plate 2 and the metal floor 3, in order to make it fixed, easy to use, adopt the first support member 4, the second support member 5 to support it. In this embodiment, the first support member 4 and the second support member 5 both use plastic screws, wherein the first support member 4 is connected to the metal floor 3 after passing through the through hole 19 and the through hole 24, and the second support member 5 passes through the through hole 21 Connect with metal floor 3. The first dielectric board 1 adopts a circular FR4 dielectric board with a thickness of 1.6mm, the second dielectric board 2 has a size of 185mm×185mm×2mm, and the metal floor 3 has a size of 200mm×200mm×2mm. The overall size of the antenna is set to 200mm×200mm×30.6mm.

Abstract

The invention discloses a broadband low-profile dual-polarized omnidirectional antenna based on an artificial magnetic conductor structure. Its structure includes a horizontally polarized loop antenna, an artificial magnetic conductor reflector structure, and a vertically polarized antenna. The polarized antenna is vertically placed, wherein the loop antenna is composed of four pairs of rotationally symmetrical printed dipoles printed on both sides of the first dielectric board (1); the artificial magnetic conductor structure is composed of a The periodic patch unit (22), the air layer between the second dielectric plate (2) and the upper surface of the metal floor (3), and the metal floor (3); the vertically polarized antenna consists of a metal cone (8), printed third The patch (25) on the upper surface of the dielectric board (11) and the short-circuit column (6) constitute. The invention is used for indoor communication of a miniature mobile communication system, and effectively reduces the section height of a dual-polarized omnidirectional antenna under the premise of ensuring antenna bandwidth and out-of-roundness.

Description

technical field [0001] The invention belongs to the technical field of antenna engineering, and in particular relates to a broadband low-profile dual-polarized omnidirectional antenna that can be used for indoor communication coverage of a micro mobile communication system. Background technique [0002] With the development of a new generation of mobile communications, micro base stations have attracted much attention due to their advantages of integration, miniaturization, low cost, and convenient installation and maintenance. One of the difficulties in designing micro base station antennas is to reduce the profile height, size and cost of the antenna as much as possible while satisfying the antenna performance. In urban and indoor communications, in addition to requiring dual-polarized, broadband, and low-profile antennas, micro base station antennas installed on indoor roofs also require horizontal omnidirectional in order to achieve 360-degree uniform coverage. characte...
