Abstract

The invention provides a double-frequency directional antenna and an unmanned aerial vehicle remote controller. The double-frequency directional antenna comprises a dielectric plate, two first dipoleantennas and two second dipole antennas, the first dipole antennas and the second dipole antennas are arranged at the same side of the dielectric plate, The length direction of the first dipole antenna and the length direction of the second dipole antenna are parallel to the X direction, the length of the first dipole antenna is 0.5 lambda1, the length of the second dipole antenna is 0.5 lambda2,the dielectric plate is provided with a symmetric line arranged in the Y direction, the first dipole antenna and the second dipole antenna are symmetrically arranged with the symmetric line as the center line, and a feeding point of the double-frequency directional antenna is arranged at the edge, parallel to the X direction, of the dielectric plate. According to the dual-frequency directional antenna and the unmanned aerial vehicle remote controller provided by the invention, the phase of the dipole antenna close to the feeding point is ahead of the phase of the dipole antenna far away from the feeding point, so that the dipole antennas with the same frequency form directional radiation pairs respectively, and the low-profile characteristic is ensured.

Description

technical field [0001] The invention belongs to the technical field of antennas, and more specifically relates to a dual-frequency directional antenna and a drone remote controller. Background technique [0002] Both civilian and military UAVs have a trend of miniaturization and high integration. For example, the civilian drone antenna, the current trend is to integrate the navigation system, image transmission system, and remote control system on the body to achieve a better interactive experience. At present, two frequency bands of WLAN are used to realize the control of the remote control and the drone. In this application scenario, the antenna on the remote control needs a directional pattern. Because generally speaking, the drone and the remote control form a positive relationship. The pattern on the back makes little contribution to the communication system. Therefore, we can conclude that the ideal state of the pattern on the remote control of the drone should be ...
