天線中的耦合應(yīng)用

文章來(lái)源: 互聯(lián)網(wǎng)    錄入: mweda.com   

大家能不能就“耦合”兩字發(fā)表一下見(jiàn)解��？尤其是在天線方面。謝謝！

網(wǎng)友回復(fù):

如何兩副天線同為接受天線，那么天線之間的耦合只是會(huì)影響兩副天線的接受頻點(diǎn) 
如何一副為發(fā)射天線，另一副為接收天線 ，耦合不但影響兩副天線的接受頻點(diǎn)，強(qiáng)的耦合會(huì)造成一幅天線的增益增大，另一幅電線接收不必要的信號(hào) ，引起噪聲

網(wǎng)友回復(fù):

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.

網(wǎng)友回復(fù):

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