Abstract

The invention discloses a low-profile broadband dual polarization omni-directional antenna. The antenna comprises a vertical polarization monopole antenna and a horizontal polarization loop antenna which are arranged side by side, and the loop antenna is composed of four rotational symmetric arc-shaped dipoles. A metal cylinder wraps a monopole feed probe to increase the monopole bandwidth, and parasitic units and directors are loaded outside dipole arms to increase impedance bandwidth of the loop antenna and gain out-of-roundness of the loop antenna on azimuth planes is reduced. The low-profile broadband dual polarization omni-directional antenna basically comprises an upper medium plate (1), a lower medium plate (2), plastic screws (3), a round patch (4), a loop patch (5), the feed probe (6), the metal cylinder (7), a metal floor (8), metal short circuit columns (9), arc-shaped printed dipoles (10), L-shaped feed baluns (11), the parasitic units (12), the directors (13), a coaxial line (14), 100 ohm microstrip lines (15) and a small metal wafer (16).

Description

technical field [0001] The invention belongs to the technical field of antenna engineering, and relates to a broadband omnidirectional antenna, in particular to a low-profile broadband high-isolation dual-polarized omnidirectional antenna applicable to the field of wireless communication. Background technique [0002] With the development of modern mobile communications, micro base stations have attracted more and more attention because of 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 and cost of the antenna as much as possible while satisfying the antenna performance. Usually, micro base station antennas require dual polarization, high port isolation, broadband, and low profile. It is suitable for micro base stations installed on indoor roofs, and the antenna is also required to have the characteristics of a horizontal ...
