Abstract: The mutual coupling effects between the base-station(BS) antennas are analyzed accurately using MoM in this paper. The analysis model of the mutual coupling between antenna is given. The mutual coupling effects between BS diversity antennas in the horizontal spaced diversity antenna system are discussed. The mutual coupling effects between the BS antenna operating at different frequencies are also analyzed according to several typical installation conditions. Some useful conclusions are also drawn from the viewpoint of mutual coupling between antennas.

Key words: base-station antenna, mutual coupling, method of moments
