| description | For high integrated antenna, certain method must be adopted achieve accurate and effective detection of amplitude and phase information of array. However, traditional method (including near-field calibration, FFT, etc.) all need to obtain phase information, so the antenna needs to provide reference channel for testing. This is contrary to the high integration of antenna, and also puts forward higher requirements for antenna designation, especially for the conformal antenna. In order to solve the problem that the traditional method relies on the parameter channel to provide reference phase, a self-reference method is designed for the near-field measurement, a test troubleshooting scenatio commonly used by high integrated antennas. The test results show that the results of the near-field test using the self-reference method are highly consistent with the test results of the traditional near-field measurement system with independent reference channel. In addition, self-reference method, which does not need a separate reference channel, is suitable for the near-field test of highly integrated antenna, which is of great significance for the field test arrangement of installed antenna. |
