Abstract

The invention discloses an FSS coating structure and electronic equipment, and relates to the technical field of antennas. The embodiment of the invention discloses the FSS coating structure, which comprises a first dielectric substrate, an antenna and an FSS coating material, wherein the first dielectric substrate comprises a first substrate surface and a second substrate surface, and the first substrate surface and the second substrate surface are two opposite surfaces; the antenna is located on the first substrate surface; and the FSS coating material is fixed to the second substrate surface and is not in contact with the second substrate surface, and the FSS coating material is used for blocking a target direction component of a radiation electric field of the antenna. In the FSS coating structure and the electronic equipment of the invention, the FSS coating structure is arranged for the antenna, and the FSS coating material in the FSS coating structure can block the target direction component of the radiation electric field of the antenna, so that the situation that the communication quality is influenced due to the fact that the radiation power is returned to reduce the SARis avoided.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an FSS cladding structure and electronic equipment. Background technique [0002] Electronic devices such as smart phones are used as communication devices, and electromagnetic waves will radiate through the antenna during wireless communication. [0003] When the electronic equipment is close to the human body, since the human body is a lossy medium, the electromagnetic field entering the human body will generate an induced current, resulting in the loss and absorption of electromagnetic energy. The dissipation of electromagnetic waves in the human body is essentially converting electromagnetic waves into heat energy. The magnitude of the energy conversion generated in this process can be measured by the physical quantity of electromagnetic wave absorption rate (Specific Absorption Rate, SAR). The higher the value, the higher the heat energy generated and the greater...
