Low-profile broadband dual polarization omni-directional antenna
TLDR
In this article, a low-profile broadband dual-polarized omni-directional antenna is proposed. But the antenna is not suitable for low-power applications, as it requires a large number of antennas to be arranged side by side.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).read more
