Claim 18:
19. A rear housing assembly for an electronic device, comprising:
a rear housing, and
a dielectric layer, arranged on an area of the rear housing, wherein the area of the rear housing is configured to be an area where an orthographic projection of a millimeter wave module of the electronic device on the rear housing is located in;
wherein the dielectric layer and a part of the rear housing in the area together form a radiation layer with gradient distribution of dielectric constant; a dielectric constant of the dielectric layer is different from that of the rear housing; the radiation layer is configured to change a beam radiation direction of millimeter wave signal transceived by the millimeter wave module.
