Background
An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space) or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing, radio astronomy and the like all use electromagnetic waves to transmit information and work by depending on antennas. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas. The same antenna is the same as the basic characteristic parameter for transmission or reception. This is the reciprocity theorem for antennas. The existing ceramic antenna for the unmanned aerial vehicle is mostly of a naked structure, is influenced by vibration when rising and falling, is easy to cause instability of the antenna structure and further influences communication performance, and has insufficient protection and poor practicability.
