Introduction of aircraft antenna

An aircraft antenna, which is a device used to radiate and receive radio waves. The principle is that the transmitter antenna will send the oscillator (transmitter) sent to the AC electromagnetic energy into a certain space of electromagnetic waves (radio waves) energy. The receiving antenna obtains electromagnetic wave energy from the surrounding space, and transmits it to the receiving device. Generally speaking, the larger the ratio of the antenna size to the wavelength, the greater the energy is obtained. The antenna has reciprocity, the same as transmitting or receiving parameters. The requirements for antenna parameters are determined by the use of radio electronic devices.
