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.
