Title:
ANTENNA ASSEMBLY AND INTERACTIVE PANEL
Document Type and Number:
WIPO Patent Application WO/2023/155156
Kind Code:
A1
Abstract:
The embodiments of the present application disclose an antenna assembly and an interactive panel. A first face of a dielectric substrate in the antenna assembly is provided with a ground plane and a closed clearance zone; a first antenna unit and a second antenna unit are provided on the first face spaced apart from each other and are located in the clearance zone, and the first antenna unit and the second antenna unit are orthogonal to each other; a radio frequency chip is provided on the dielectric substrate and is electrically connected to the first antenna unit and the second antenna unit; and a metal resonant cavity is provided on a second face of the dielectric substrate, and in a direction perpendicular to the second face, at least part of a projection of the clearance zone on the metal resonant cavity is within an outer contour of the metal resonant cavity. In this way, after being reflected, an electromagnetic wave radiated from the first antenna unit and the second antenna unit to the metal resonant cavity faces the direction of the first face, such that the intensity of an electromagnetic wave radiated from the side of the first face is enhanced; in addition, the antenna units are arranged in the closed clearance zone, and traces of the antenna units are simplified to reduce the area of the dielectric substrate, such that the antenna assembly is smaller.
