Abstract

The invention relates to a wide-bandwidth beam dual-polarization directional antenna that can conform to a metal carrier, and belongs to the technical field of antennas. Including metal cavity, radiation cover, two microstrip balun substrates and RF connectors, the metal cavity wraps the entire antenna, the radiation cover fits with the upper surface of the metal cavity, and the microstrip balun substrate is used to carry the microstrip matching circuit , the RF connector is connected to the feeding hole on the microstrip matching circuit. The radiation cover of the present invention adopts the design of criss-cross gaps, and adopts microstrip balun matching circuits to feed power respectively. The metal radiation sheet on the surface of the radiation cover is connected with the entire metal cavity, and the metal radiation sheet on the surface of the radiation cover is divided into four pieces. The two radiation sheets on each diagonal are called a pair of radiation units. When two pairs When the radiating elements are excited at the same time, dual-polarized radiation is formed, and a directional pattern can be obtained directly above the antenna. At the same time, the antenna can be applied to the surface of the metal carrier for conformal design.

Description

Technical field [0001] The present invention belongs to the field of antenna technology, relates to a wide bandwidth beam bipolar directional antenna that can be co-shaped with a metal carrier, specifically for a metal carrier surface that is not suitable for destroying the surface shape. Background [0002] Magnetic current antennas can operate in close metal environments, have small backward levels, have wide beam characteristics, and can cover a considerable radiation range. Dual-polarized antennas can transmit or receive two quadrature polarized electromagnetic waves at the same time, so in the same frequency band, dual-polarized antennas can achieve the role of two antennas, which can reduce antenna costs and installation space. At present, dual-polarized magnetic current antennas have great application prospects in conformal designs with metal surfaces. [0003] Commonly used magnetic current antenna forms are microstrip magnetic current antennas. Microstrip magnetic flow a...
