A novel full 2-port calibration method for antenna measurements using sol standards without through procedure

We have proposed a novel method to calibrate a vector network analyzer (VNA) using only Short-Open-Load (SOL) standards without Thru (T) procedure in a full 2-port calibration, which is especially suitable for reciprocal antenna measurements because of the easiness of its procedure, and have shown that the systematic uncertainty is almost the same as that of the SOLT calibration method. In this paper, we show that there is the similar condition on the signal to noise ratio (SNR) for the calibration methods. Therefore, it is proved that the method is simpler than the SOLT calibration method with equivalent effectiveness.
