Abstract

The invention discloses an electromagnetic scattering film and an electronic device comprising the same, and the electromagnetic scattering film comprises a metal layer; a through hole penetrating through the upper surface and the lower surface of the metal layer is formed in the metal layer, and the maximum value of the distance s between any two points on the outline of the section of the through hole is smaller than the wavelength [lambda] of microwaves entering the through hole, so that the microwaves are diffracted after entering the through hole. The through holes with the wavelength smaller than that of microwaves are formed in the metal layer, the microwaves which are linearly transmitted originally can generate diffraction after entering the through holes, and the microwave transmitting and / or receiving space range is enlarged.

Description

[0001] This invention requires the priority of the following two Chinese patent applications. 1. The application date is: June 5, 2019, and the application number is: 201920847012.6; 2. The application date is: June 05, 2019, and the application number is: 201910489146 .X, the entire contents of which application is incorporated by reference into this application. technical field [0002] The invention relates to the technical field of communication, in particular to an electromagnetic scattering film and an electronic device including the electromagnetic scattering film. Background technique [0003] Microwave communication is communication using electromagnetic waves with wavelengths between 0.1 millimeters and 1 meter. The frequency range corresponding to the electromagnetic wave in this wavelength band is 300MHz (0.3GHz)-3THz. Microwave communication is directional due to the characteristics of microwave straight-line transmission. When the user is not in the specified ...
