Error test direction for antenna groups and automatic calibration system and / or calibration method of antennas

摘要

The present invention relates to an error test direction for antenna groups and an automatic calibration system and / or calibration method of antennas. In the case of the invention, the gain is analyzed by means of a signal analyzer, in order to compensate for the amplification of the wire /. Thereafter, by means of a dc - offset - generator a known dc - offset is generated, which is added in the signals. Thus, the phase offset with the comparing of the original signals at the receiving terminal, in order to calibrate the antennas. In this way, the difficulty of the system is taken into account is reduced and the calibration time being reduced of the antennas can be shortened.n="30"
