Abstract

This paper reports on a new method of measuring the phase characteristics of an antenna using the Doppler frequency measurement technique. With this method, the antenna being tested is rotated at a rate of f_sp around an axis through its geometrical center, and the phase characteristics of the antenna are calculated from the harmonic components of f_sp during time variations in the Doppler frequency of radio waves emitted from the antenna. Using this, we obtained three-dimensional phase characteristics of a patch antenna with a root-mean-square error of about 0.5°, and confirmed its efficacy through experimental results.
