Title:
ANTENNA ASSEMBLY AND WIRELESS DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/077718
Kind Code:
A1
Abstract:
Disclosed are an antenna assembly and a wireless device, belonging to the technical field of communications. The antenna assembly comprises N elements, a feed network and a printed circuit board (PCB), wherein N is an integer greater than or equal to four, the N elements and the feed network are all located on the PCB, and the N elements are all connected to the feed network. Each element is provided with a radial part, the radial part of each element points to an antenna phase center, and the length of the radial part of each element is greater than the sum of the lengths of the other non-radial parts. In this way, a main radiation direction of each element is consistent with the direction of the radial part. Therefore, each element is equivalent to a line source, a beam width is relatively narrow, and a minor-lobe shift inhibition capability is enhanced.
