Abstract
A radio wave receiving system comprises an antenna having at least two antenna elements, a phase shifter connected to at least one of the antenna elements, and a combiner for combining signals passed through the phase shifter and other signals not passed through the phase shifter. Through proper control of the mutual phase difference between signals from the aforementioned antenna elements by using the phase shifter, the system alters the polarization characteristic of the antenna in the direction of incidence of undesired reflected waves and consequently supresses the fading due to undesired reflected waves.
