Embodiment 1

[0028] see Figure 1 ~ 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 an artificial magnetic conductor structure-based broadband low-profile dual-polarized omnidirectional antenna, which structurally comprises a horizontally polarized loop antenna, an artificial magnetic conductor reflection plate structure and a vertically polarized antenna, wherein the horizontally polarized loop antenna and the vertically polarized antenna are vertically placed; the loop antenna comprises four pairs of rotationally symmetrical printed dipoles printed on two sides of a first dielectric plate (1); an artificial magnetic conductor comprises periodic patch elements (22) which are printed on the upper surface of the first dielectric plate (1), an air layer between a second dielectric plate (2) and the upper surface of a metal floor (3) and the metal floor (3); and the vertically polarized antenna comprises a metal cone (8), a patch (25) printed on the upper surface of a third dielectric plate (11) and a short-circuit pole (6). The artificial magnetic conductor structure-based broadband low-profile dual-polarized omnidirectional antenna is applied to indoor communication of a miniature mobile communication system and effectively reduces the profile height of the dual-polarized omnidirectional antenna under the premise of ensuring the antenna bandwidth and the non-circularity.

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...
