Description

Technical Field

[0001] The present application relates to the technical field of metasurface antennas, and in particular to a metasurface antenna detection method and system based on magnetic field. Background Art

[0002] In recent years, antennas have been applied to intelligent electrical devices. The antennas are stimulated to generate detection microwaves with an initial polarization direction. The detection microwaves detect the activity status of users in a target area in a manner that the detection surface covers the target area, so that the intelligent electrical devices can adjust the working status and working mode according to the user's activity status to provide users with intelligent and humanized services.

[0003] Metasurface refers to an artificial layered material with a thickness less than the wavelength. Metasurfaces can achieve flexible and effective control of the polarization, amplitude, phase, polarization mode, propagation mode and other characteristics of electromagnetic waves; according to the type of waves being controlled, metasurfaces can be divided into optical metasurfaces, acoustic metasurfaces, mechanical metasurfaces, etc. Optical metasurfaces are the most common type. They can control the polarization, phase, amplitude, frequency and other characteristics of electromagnetic waves through sub-wavelength microstructures. They are an emerging technology that combines optics and nanotechnology.

[0004] Therefore, a metasurface detection antenna that combines metasurface technology and antenna detection technology has now appeared, that is, a metasurface lens is set on the detection antenna, and the optical metasurface is used to regulate electromagnetic waves for detection and communication. For example, the Chinese patent invention patent CN111600123A provides a metasurface antenna. The metasurface antenna includes a first substrate, a second substrate, a third substrate, a fourth substrate, a metasurface structure, a radiation patch, a ground plate, a directional differential feeding network and a capacitive matching network. The above invention technical solution is electrically connected to the radiation patch through two signal output ends of the directional differential feeding network, and the directional differential feeding network performs differential feeding to the radiation patch through the two signal output ends, so that the radiation patch generates a directional radiation source, a capacitive matching network is arranged in the second substrate and the third substrate, and a ground plate is arranged between the third substrate and the fourth substrate. The capacitive matching network is connected to the radiation patch so that the radiation patch generates an omnidirectional radiation source, and the metasurface structure receives the directional radiation source and / or the omnidirectional radiation source, and widens the frequency band width of the directional radiation source and / or the omnidirectional radiation source, and increases the gain of the directional radiation source and / or the omnidirectional radiation source.

[0005] However, the metasurface lens structure is set on a plane, resulting in poor detection accuracy. In order to avoid this defect, multiple metasurface lens antennas should be set and set at different positions to form different planes. Simultaneous detection by multiple metasurface detection antennas can obtain greater detection accuracy. However, the positions of multiple metasurface antennas are different. If they are not accurately detected, the detection target may be lost, resulting in detection accuracy that is worse than that of a single-plane detection antenna.

[0006] Therefore, a magnetic field-based metasurface antenna detection method and system are expected to adjust the metasurface units with multi-plane designs at different positions, thereby improving the detection accuracy of the metasurface antenna. Summary of the invention
