本发明实施例涉及通信技术领域，尤其涉及一种谐振单元和介质滤波器。
背景技术
近年来，滤波器作为通信天馈系统的重要组成部分，是绕不开的关键器件，滤波器的研究也在不断地取得新进展。滤波器是由电容、电感和电阻组成的滤波电路。滤波器可以对电源线中特定频率的频点或该频点以外的频率进行有效滤除，得到一个特定频率的电源信号，或消除一个特定频率后的电源信号。随着移动通信技术的发展，对滤波器的要求越来越高，如低频率、低成本、高功率、高性能等等。特别是产品小型化的需求越来越广泛。尤其是在低频段的产品上，传统设计的体积太大，已无法满足新的市场需求。长期以来，人们一直在探索如何减小低频产品的体积，常见的降低频率的方法有金属谐振杆加金属圆盘方式，但是在小体积情况下无法提升单腔Q值从而导致插入损耗较大。另外通过TE模或TM模介质谐振器能够提升Q值，但是无法满足体积又小频率又低的需求，且介质谐振器其高昂的成本限制了其应用范围。所以如何在保持单腔小体积的情况下，实现大幅度降低频率是基站滤波器供应商面对市场挑战所需要解决的问题。
