Abstract

The embodiment of the invention relates to the technical field of unmanned aerial vehicle antennas, and discloses a dual-frequency antenna and an unmanned aerial vehicle. The dual-frequency antenna comprises a substrate, a monopole oscillator which has a first resonant frequency, wherein the monopole oscillator is arranged on the substrate and comprises a first radiation part and a second radiation part, and the first radiation part and the second radiation part are located on the two opposite sides of a feeding point of the monopole oscillator respectively; a dipole oscillator which has a second resonant frequency, wherein the dipole oscillator is arranged on the substrate and located between the first radiation part and the second radiation part; and a feed coaxial line, wherein the feed end of the feed coaxial line is respectively connected with a feed point of the monopole oscillator and a feed point of the dipole oscillator, and a grounding end of the feed coaxial line is connected with a grounding end of the dipole oscillator. Therefore, when the dual-frequency antenna is installed in the unmanned aerial vehicle, the dual-frequency antenna can be contained in the undercarriage while the task information transmission quality is guaranteed, the built-in space size requirement is met, and the miniaturization design of the unmanned aerial vehicle is facilitated.

Description

Technical field [0001] The present invention relates to the field of drone antennas, in particular to a dual frequency antenna and an unmanned aircraft. Background technique [0002] Unmanned aircraft is a non-supported aircraft that uses radio remote control equipment and the self-propelled program control. The wireless communication link system is an important part of the unmanned aircraft system for establishing an airborne bidirectional data transmission channel to complete the long-distance remote control, telemetry and task information transmission of the drone. [0003] The existing wireless communication link system is generally divided into an airborne portion and the ground portion. The airborne portion includes an onboard data terminal (ADT) and an antenna, the onboard data terminal includes an RF receiver, a transmitter, and a modem for connecting the receiver and the transmitter to other parts of the system. The ground portion is also known as the ground data termina...
