Abstract

一种减少天线受到无线电磁波干扰的装置，采用带电磁波进出口的阻挡包围方法，用电磁波阻挡材料把WIFI天线包围在里面，形成一个包围着WIFI天线的包围体，该包围体留有一个或多个电磁波信号进出口，这样就形成一个电磁波选择罩（波选罩），在波长长度条件满足情况下，让信号强度足够，或强度不完全足够但方向适合，或方向不完全适合但强度条件好的电磁波能进入该罩和天线进行通信，减少或消除罩外其它电磁波对罩内天线的干扰，主要用于减少或消除同频干扰或邻频干扰。本发明能很好的减少WIFI路由器受到的同频或邻频干扰，能使手机等设备的WIFI上网网速更稳更快。本发明经实际测试，效果很好，网速明显变的更稳更快。
