An open ring resonator (ORR) loaded with a varactor diode is designed and implemented in order to achieve high-performance tunable band-stop filters in planar technology with a compact size. This varactor-loaded ORR (VLORR) is versatile. It allows a shunt connection with different planar waveguide sections. In this paper, it has been connected to a coplanar waveguide (CPW) and a half-mode substrate integrated waveguide (HMSIW). As a reverse bias voltage is applied to the VLORR, a continuous tuning over the resulting stop-band can be achieved. To illustrate the possibilities of the VLORR, three prototypes have been designed, fabricated, and characterized. The three prototypes show an outstanding performance, with a rejection level at the resonant frequency and a tuning range greater than 12 dB and 85%, respectively. This VLORR has high potential value in microwave communication systems to eliminate unwanted signals.
为了在平面技术中实现具有紧凑尺寸的高性能可调谐带阻滤波器，设计并实现了一种加载变容二极管的开环谐振器（ORR）。这种加载变容二极管的ORR（VLORR）具有通用性。它允许与不同的平面波导段进行并联连接。在本文中，它已连接到共面波导（CPW）和半模基片集成波导（HMSIW）。当向VLORR施加反向偏置电压时，可以在所得的阻带范围内实现连续调谐。为了说明VLORR的可能性，设计、制作并表征了三个原型。这三个原型表现出优异的性能，在谐振频率处的抑制水平和调谐范围分别大于12 dB和85%。这种VLORR在微波通信系统中具有很高的潜在价值，可用于消除不需要的信号。
