Title:
EXTERNAL DUAL-BAND ANTENNA FOR UNMANNED AERIAL VEHICLE, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/206286
Kind Code:
A1
Abstract:
An external dual-band antenna for an unmanned aerial vehicle, and an unmanned aerial vehicle. The antenna comprises a substrate (1), low-frequency oscillator regions, high-frequency oscillator regions, a feed coaxial line (4), and ground terminals (5); the two ground terminals (5) are separately electrically connected to the feed end of the feed coaxial line (4); the low-frequency oscillator regions or the high-frequency oscillator regions are provided with a receiving area (2111) used for disposing the feed coaxial line (4); the low-frequency oscillator regions comprise a first low-frequency oscillator region (21) and a second low-frequency oscillator region (22) arranged on the front and back surfaces of the substrate (1) in a vertically asymmetric manner; the high-frequency oscillator regions comprise a first high-frequency oscillator region (31) and a second high-frequency oscillator region (32) arranged on the front and back surfaces of the substrate (1) in a vertically asymmetric manner. The external dual-band antenna for an unmanned aerial vehicle designed to have the structure can meet wiring requirements in a small space so that the circuit layout is more reasonable, and can also achieve signal coverage of dual frequency bands, i.e., 2.4 GHz and 5.8 GHz.
