提出了一种具有180度以上相移的反射型模拟移相器，用于射频信号处理。它由CRLH和RH传输线和谐振电抗电路组成的缩小尺寸的大鼠赛跑耦合器组成。在CRLH传输线中，并联电感可以通过并联变容谐振器来减小电感的电感。这种设计可以增加可变相位范围，并可能减小移相器的尺寸。
A reflection-type analog phase shifter with more than 180-degree phase shift was proposed for RF signal processing. It was composed of a reduced-size rat-race coupler consisting of CRLH and RH transmission lines and resonating reactance circuits. The inductance of shunt inductors in CRLH transmission lines could be reduced by resonating varactors parallelly connected to the inductors. This design enables an increased variable phase range and potentially a decreased phase shifter size.
