我们提出了一种新型的传输高温超导（HTS）双模双带八角形贴片谐振器滤波器，外加贴片导体作为扰动。双模双带谐振器由两个堆叠的八角形贴片谐振器和一个附加的贴片导体组成，该贴片导体放置在谐振器之间以提供正交谐振模式之间的耦合。与具有短段摄动的传统双模滤波器相比，这降低了摄动处的电流浓度。通过改变附加贴片导体的尺寸来调节带宽。利用基于矩量法的电磁模拟器设计了一种中心频率为5.0GHz、带宽为100MHz、外加贴片导体的2极HTS双模双带八角形谐振器滤波器。滤光片是用YBa2CuO7薄膜在r-Al2O3衬底上制备的。通过实验和仿真验证了该滤波器的有效性。
We propose a novel transmit high-temperature-superconducting (HTS) dual-mode double-strip octagonal patch resonator filter with an additional patch conductor working as a perturbation. The dual-mode double-strip resonator consists of two stacked octagonal patch resonators and an additional patch conductor which is placed between the resonators to provide coupling between the orthogonal resonating modes. This reduces the current concentration at the perturbation compared with that of conventional dual- mode filter with stub perturbation. The bandwidth is adjusted by changing the size of the additional patch conductor. A 2-pole HTS dual-mode double-strip octagonal resonator filter using an additional patch conductor with a 5.0GHz center frequency and 100MHz bandwidth was designed using an electromagnetic simulator based on the moment method. The filter was fabricated using YBa2CuO7 thin films on r-Al2O3 substrates. The filter is evaluated by experiment and simulation with good agreement.
