An antenna system

The present invention relates to communication field, and particularly relates to an antenna system, comprising: a transmitting antenna, a receiving antenna, said transmitting antenna positioned and above the receiving antenna radome, and a reflector positioned within the radome, transmitting signals via the reflector after reflection of the transmit antenna to the receive antenna signal and the transmit antennas transmit signals directly to the receive antenna co-channel interference generated signals cancel each other. Thus, embodiments of the present invention may be in the case of increasing the number of antennas without additional and increasing distance from the antenna, with the antennas to achieve transmit receive antenna pilot interference cancellation signal.
