Abstract :
In this study, we obtain periodically time-variable antenna pattern of the antenna based on the equivalent weight vector method with approximated continuous reactance. According to the antenna pattern we analyze the received signal spectra which are frequency-shifted by the time-variable antenna pattern. We compare the spectra to those obtained by the experiments and verify the antenna pattern analysis.
