Title:
DUAL-BAND ANTENNA SYSTEM AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/082679
Kind Code:
A1
Abstract:
Disclosed are a dual-band antenna system and a terminal device. The dual-band antenna system comprises a substrate, two ends of the same side of the substrate are respectively provided with a dual-band antenna assembly, the dual-band antenna assembly comprises a low-frequency WiFi radiation sheet and a high-frequency WiFi radiation sheet, the two high-frequency WiFi radiation sheets are located between the two WiFi radiation sheets, and the polarization directions of the two low-frequency WiFi radiation sheets are orthogonal. According to the present application, by respectively using two high-frequency WiFi radiation sheets and two low-frequency WiFi radiation sheets, the frequency division and independence of high frequency and low frequency are implemented, and radiation patterns of the two high-frequency WiFi radiation sheets themselves are omnidirectional in a horizontal plane, so that low-profile single-antenna vertical polarization horizontal omnidirectional coverage can be implemented; the two low-frequency WiFi radiation sheets are orthogonally arranged in the polarization direction, thereby implementing omnidirectional coverage, avoiding metal reflection, avoiding the occurrence of a communication blind region, and improving anti-metal performance.
