Description

technical field [0001] The present invention relates to an antenna measurement method and device, in particular to a drone-based antenna performance measurement method and device. Background technique [0002] Antenna is an essential tool for sending and receiving electromagnetic waves. Antenna gain and pattern are two important parameters to measure antenna performance. When it is difficult to obtain the antenna gain and directional pattern accurately by means of theoretical calculation, it is necessary to measure the antenna gain and directional pattern in the laboratory. During the measurement, the antenna to be tested is placed on a controllable turntable, the transmitting antenna is placed at a fixed position horizontal to the antenna to be tested, and the distance R between the two antennas meets the far-field test conditions, R>10λ, where λ is the test wavelength. The transmitting antenna and the antenna to be tested are respectively connected to the two ports of ...
