Abstract

本发明实施例提供了一种用于通信的射频RF天线、微波设备和通信系统，其中，该RF天线包括天线罩，所述天线罩具有前端；光学部件，所述光学部件位于所述天线罩内，用于接收经过所述前端的RF信号，所述光学部件具有光轴；以及滤波层，所述滤波层位于所述前端和所述光学部件之间，并且垂直于所述光轴设置；所述滤波层具有小于1的折射率n，以形成全反射入射的阈值角度arcsin(n)，使得在滤波层上的入射角小于所述阈值角度的RF信号发生透射，在滤波层上的入射角度大于或等于所述阈值角度的RF信号发生全反射来实现滤波。本发明实施例提供的RF天线能够解决干扰抑制的过程对目标业务信号造成影响的问题，应用场景不受限制。
