Abstract

The invention discloses a four-frequency dual-polarized antenna and a wireless communication device. The four-frequency dual-polarized antenna comprises a first metal layer, a first substrate integrated waveguide, a second metal layer, a second substrate integrated waveguide and a metal floor which are arranged in sequence from top to bottom, wherein the first metal layer is provided with a rectangular ring radiation gap; the middle portion of the second metal layer is provided with a cross-shaped coupling gap; rectangular coupling gaps are respectively arranged at four sides of the cross-shaped coupling gap, the middle portion of the second substrate integrated waveguide is provided with a feed through hole, and the metal floor is provided with a circular gap arranged on the correspondingposition of the feed through hole; and the wireless communication device comprises the antenna mentioned above. The antenna employs the coaxial feed excitation mode to couple the energy at the upperportion through different coupling gaps and from different paths and radiate the energy by the rectangular ring radiation gap, and the antenna is compact in structure, low in profile and stable in radiation pattern and can achieve simple and adjustable four-frequency dual-polarized performances.

Description

technical field [0001] The invention relates to an antenna, in particular to a quad-frequency dual-polarization antenna and wireless communication equipment, and belongs to the technical field of wireless communication antennas. Background technique [0002] As an important part of modern wireless communication technology, Substrate Integrated Waveguide (SIW) has excellent characteristics of low profile and low loss, and is easy to integrate with planar devices, simple and cheap to process, and can be mass-produced. Antennas based on substrate-integrated waveguides often have higher gain due to their high power capacity, especially when it comes to high frequency bands. The low electromagnetic leakage characteristics of SIW make them have better advantages than traditional microstrip circuits. [0003] With the development of technology, modern wireless communication systems are widely used in various fields of life, but in practical applications, multiple frequency bands ar...
