Title:
WAVE ABSORBING STRUCTURE, ANTENNA, RADAR, AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2023/231027
Kind Code:
A1
Abstract:
The present application discloses a wave absorbing structure, an antenna, a radar, and a terminal. The wave absorbing structure comprises a resonance portion, a load, and a wave absorbing portion; the resonance portion can be configured to resonate with an antenna unit for radiating a signal in an antenna; when the resonance portion resonates with the antenna unit, the resonance portion can couple and receive energy from the antenna unit; the resonance portion can feed power to the load, so as to transfer the energy to the load; and the wave absorbing portion is configured to cover the load, so that the energy of the load can be absorbed. Therefore, the energy of the antenna unit coupled to the wave absorbing structure is absorbed, so that the surface wave of the antenna unit can be reduced, thereby realizing improvement of the consistency of an antenna pattern, and further being capable of improving the detection precision of the radar.
