Outstanding directionality can help reducing noise and improving SNR ratio, and can dig out weak signals that are overwhelmed by noise when the conventional antennas are received. By rotating the antenna so that the dummy point of the antenna is aligned with the interference signal, the specific near-field interference can be attenuated to the maximum.
