Abstract

The present disclosure relates to an antenna device and a drone, and belongs to the field of electronic technology. The antenna device includes a radio frequency feeder, a radiation unit, N strip-shaped parasitic units, N electric control switches and a radio frequency ground wire. The radio frequency feeder is electrically connected with the radiation unit, and the radio frequency feeder is used for electrical connection with the modem. The N parasitic units are respectively electrically connected to the radio frequency ground wire, and the N electric control switches are respectively arranged on the connection lines between the N parasitic units and the radio frequency ground wire. N parasitic units are evenly arranged around the radiation unit, and the N parasitic units are respectively parallel to the main axis of the radiation unit. With the present disclosure, only one antenna device is required to cover all directions in space, and the volume of the antenna device provided by the embodiments of the present disclosure is greatly reduced.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to an antenna device and a drone. Background technique [0002] In the process of sending information from the UAV to the control terminal on the ground, the information can be transmitted through the antenna device on the UAV. The antenna device is a kind of energy converter, which can convert the high-frequency electrical signal propagating on the radio frequency feeder into electromagnetic waves propagating in free space. The antenna device may be a directional antenna, which has a strong signal transmission capability in a certain direction in space. Multiple antenna devices can be installed in the UAV to enhance the signal transmission capability in all directions in space. [0003] The shape surrounded by the plurality of antenna devices may be a regular nine prism, and each antenna device is arranged on each cylindrical surface of the regular nine prism. When ...
