Abstract

The invention provides a shark fin antenna, comprising a substrate and a plurality of radiation branches arranged on the substrate. The plurality of radiation branches comprise a first radiation branch configured to serve as emitters at a first part of a first resonance frequency band and a second resonance frequency band, a second radiation branch arranged on one side of the first radiation branch and configured to serve as a second emitter in a first part of the first resonance frequency band and serve as a reflector in a second resonance frequency band, and a third radiation branch arranged on the other side of the first radiation branch and configured to serve as a director in the second resonance frequency band. The invention also discloses a corresponding antenna system and a vehicle. According to the scheme, the number of cables between the antenna and the receiver can be reduced, so that the corresponding production and assembly cost is saved, and larger directional gain can be obtained.

Description

technical field [0001] The present invention generally relates to the technical field of vehicles, and more specifically, relates to a shark fin antenna, an antenna system including the shark fin antenna, and a vehicle. Background technique [0002] Shark fin antennas are widely used in automotive communication systems due to their beautiful appearance and excellent performance. In shark fin antennas, dipole, monopole and patch antennas are usually designed to cover different communication frequency bands. Usually, a shark fin antenna includes multiple independent antenna units, and is connected to different antenna units through multiple cables. [0003] At present, the problem of multi-cables is solved by setting a plurality of radiation branches connected to the feed board. A plurality of radiating branches provides a multi-band antenna element and thus a multi-band antenna element with a single feed. [0004] The inventor realizes that there is room for further improv...
