天线中的耦合应用

大家能不能就“耦合”两字发表一下见解啊？尤其是在天线方面。谢谢！

网友回复:

如何两副天线同为接受天线，那么天线之间的耦合只是会影响两副天线的接受频点 
如何一副为发射天线，另一副为接收天线 ，耦合不但影响两副天线的接受频点，强的耦合会造成一幅天线的增益增大，另一幅电线接收不必要的信号 ，引起噪声

网友回复:

耦合 should be mutual couping. for the antennas in separate systems, the MC is a interference to each other even they are working in different frequencies. in multi-antenna systems, such as MIMO or diversity systems, the MC will cause correlation to degrade the system performance such as capacity.

网友回复:

however, the MC can be used to control radiation performance in multiple antenna systems to achieve space diversity.
