Title:
ANTENNA ASSEMBLY CAPABLE OF PROXMITY SENSING AND ELECTRONIC DEVICE WITH THE ANTENNA ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2023/130418
Kind Code:
A1
Abstract:
An antenna assembly capable of proximity sensing and an electronic device including the antenna assembly are provided. The antenna assembly includes a first antenna element being driven for communication in a frequency band of radio frequency RF signals; a second antenna element positioned in vicinity of the first antenna element and electrically isolated from the first antenna element, the second antenna element being parasitically coupled to the first antenna element; a first filter coupling the second antenna element to ground; and a second filter coupling the second antenna element to a proximity sensing circuit, the proximity sensing circuit driving the second antenna element to detect proximity of a capacitive object to the antenna assembly. The antenna assembly requires limited space for supporting proximity sensing, and has lowered cost.
