Title:
OMNIDIRECTIONAL ANTENNA SYSTEM AND DRONE MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/200838
Kind Code:
A1
Abstract:
An omnidirectional antenna system (100) and a drone monitoring device. The omnidirectional antenna system (100) comprises at least one circular array of antennas (40) arranged in a predetermined direction. The at least one circular array of antennas (40) has a common axis at the center, and each of the at least one circular array of antennas (40) comprises a plurality of antenna structures (50) having the same frequency band and evenly distributed along a circumference of the circular array. Since the plurality of antenna structures (50) are evenly distributed along the circumference, the invention can realize a high-gain omnidirectional antenna system (100) having good omnidirectional radiation and signal receiving capabilities and anti-interference performance in all directions on a horizontal plane. The invention can resolve the issues of a common drone monitoring device of a short monitoring distance and significant disparities in monitoring performances in different directions, and can also resolve the issue in which a common drone monitoring device is susceptible to electromagnetic signal noise interference.
