| Abstract(in English) | In order to realize full duplex radio communication, we have proposed an interference reduction technique, which combines an end-fire array(EFA) antenna and an eigen-beamforming method. We already have evaluated it by calculation and experiment, which showed that amplitude differences among multiple-input multiple-output(MIMO) propagation paths degrade an effect of the interference reduction. This report proposes a rotationally-symmetrical array(RSA) antenna, which causes neither amplitude nor phase differences in above scenario. We simulate the residual interference power after a null-steering of the proposed method, with evaluating distance between a transmitting(Tx) array and a receiving(Rx) array to achive -50dB interference power. Simulation shows that RSA needs 0.51 times aperture length than EFA, while array length of Tx and element spacing of Rx are 3 wavelengths and 1 wavelength, respectively. |
