The invention relates to the field of mobile communication, in particular to a polarization-adjustable circular polarization patch array antenna and a polarization regulation and control method. The polarization-adjustable circularly polarized patch array antenna comprises an upper dielectric substrate, wherein the upper dielectric substrate comprises a plurality of right-handed circularly polarized antenna units and left-handed circularly polarized antenna units which are arranged at intervals; the middle-layer dielectric substrate is arranged on the side, away from the right-handed circularly polarized antenna unit and the left-handed circularly polarized antenna unit, of the upper-layer dielectric substrate, and a substrate integrated waveguide structure is formed on the middle-layer dielectric substrate; and the lower-layer dielectric substrate is arranged on one side, deviating from the upper-layer dielectric substrate, of the middle-layer dielectric substrate, a bias circuit is formed on the lower-layer dielectric substrate, and the bias circuit is used for controlling the radiation state of the right-handed circularly polarized antenna unit and / or the left-handed circularly polarized antenna unit. According to the array antenna, polarization can be freely switched while circular polarization is achieved, and the antenna is very compact in overall size and easy to integrate.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a circularly polarized patch array antenna with adjustable polarization and a method for adjusting and controlling the polarization. Background technique [0002] In recent years, Substrate Integrated Waveguide (SIW) has been widely used in the design of passive devices such as filters and power splitters and slot array antennas due to its planar structure characteristics, and because of its relatively microstrip transmission structure Reduced conductor loss results in a significant reduction in its own loss. At the same time, the size and weight of the substrate integrated waveguide have been greatly improved compared with the traditional rectangular waveguide, and because the PCB multilayer board manufacturing process has become increasingly mature, the processing difficulty and processing cost of SIW are greatly reduced, which is also an important factor for SIW. The reali...
