The invention discloses an antenna decoupling structure and method based on a polarized rotating surface. The antenna decoupling structure comprises an antenna array composed of at least two antenna units and a polarized rotating surface structure placed between the two adjacent antenna units. The polarized rotating surface structure comprises a plurality of resonance units arranged periodically and a dielectric substrate supporting the resonance units, the dielectric substrate is perpendicular to the floor of the antenna array, and each resonance unit comprises a first resonance structure and a second resonance structure which are arranged on the two opposite sides of the dielectric substrate respectively and correspond to each other in position. The resonance units are used for enabling electromagnetic waves to enter from one side of the dielectric substrate, and the electromagnetic waves are transmitted to the other side of the dielectric substrate through polarization rotation to be emitted out. The polarization mode of electromagnetic waves in the polarized rotating surface structure is rotated by 90 degrees by placing the polarized rotating surface structure between the two adjacent antenna units, so that the space wave coupling between the antenna units can be effectively reduced, and the isolation between the antenna units is improved.
Description
technical field [0001] The invention belongs to the field of wireless communication, and relates to an antenna decoupling structure and method based on a polarization rotating surface. Background technique [0002] Whether it is in modern communication, navigation, remote sensing, satellite systems, or equipment that requires multiple antennas such as aircraft, drones, ships, vehicles, and handheld terminals, more and more different antennas are needed. With the development of high integration and miniaturization of various communication equipment, coupled with the limited internal space of the equipment, the distance between the antennas is getting smaller and smaller, and the problems of mutual coupling and crosstalk between them are intensified, which is easy to affect the independent working performance of each system, resulting in equipment Overall work performance is reduced. [0003] For example, in order to adapt to the requirements of modern navigation, ships conti...
