Abstract

Calibrated antennas are must for a certified EMC laboratory. A study has been conducted for calibrating antennas in the frequency range 200 MHz-1 GHz, which are needed for 1 meter radiated emission testing-RE02 of MIL-STD-461C. Measurements were conducted to ascertain the antenna factor for conical log spiral antenna by adapting 'Identical Two Antenna Method of calibration'. These measurements were conducted in the frequency range of 200 MHz-1 GHz. The test results indicate the measured antenna factors within +/- 1 dB of the nominal values supplied originally by the manufacturer.

一种实用的天线校准方法

经过认证的EMC实验室必须对天线进行校准。对MIL-STD-461C 1米辐射发射测试所需的200 MHz-1 GHz频段天线进行了标定研究。采用“同双天线定标法”对锥形对数螺旋天线的天线系数进行了测量。这些测量是在200 MHz-1 GHz的频率范围内进行的。测试结果表明，测量到的天线系数在制造商最初提供的标称值的+/- 1db范围内。
