An antenna assembly includes a dielectric substrate, wherein a first surface of the dielectric substrate includes a ground plane and a closed clearance region located in the ground plane; a first antenna unit and a second antenna unit, the first antenna unit and the second antenna unit being spaced apart on the first surface of the dielectric substrate and located in the closed clearance region, and the first antenna unit and the second antenna unit being orthogonally arranged; a radio frequency chip, arranged on the dielectric substrate and connected with the first antenna unit and the second antenna unit respectively; and a metal resonant cavity, arranged on a second surface of the dielectric substrate, wherein in a direction perpendicular to the second surface, at least a part of a projection of the closed clearance region on the metal resonant cavity is within an outer contour of the metal resonant cavity.

Antenna assembly and interactive white board

An interactive white board includes a display screen, a metal backboard, an antenna assembly, and a mainboard, wherein the metal backboard is located behind the display screen, and is provided with through holes, the antenna assembly is disposed on a surface of the metal backboard facing away from the display screen, and is located in a display region of the display screen, the antenna assembly is disposed directly opposite to the through holes, the mainboard is provided on the surface of the metal backboard facing away from the display screen, and the antenna assembly is electrically connected with the mainboard.

Interactive white board

An antenna assembly and an electronic device are provided. The antenna assembly comprises a dielectric substrate; an antenna unit, arranged on a surface of the dielectric substrate; a radio frequency chip, arranged on a surface of the dielectric substrate, and connected with the antenna unit; and a metal shielding cover, arranged on another surface of the dielectric substrate facing away from the antenna unit, and coving the antenna unit. The electromagnetic interference to antenna unit caused by other electronic devices of electronic equipment can be isolated through the metal shielding cover, and the antenna unit and the radio frequency chip of the antenna assembly can be arranged on the same dielectric substrate, avoiding the use of a coaxial cable to connect the antenna unit and the radio frequency chip, thereby solving the problem of electromagnetic interference to and ensuring the radiation performance of the antenna unit.
