悬置带状线是一种具有许多优点的传输线介质，但由于有效介电常数接近于1，分布元件通常体积较大。本文介绍了一种结构紧凑、损耗低的新型SSL谐振器。为此，在谐振器的开路侧附近，将长方体形状的金属砖结合到SSL通道中。通过这种电容负载，谐振器所占的面积可以减少约5倍，但仍保持高品质因数。以中心频率为670 MHz的带通滤波器为例，验证了这种新型谐振器的可行性，该滤波器具有体积小、插入损耗低的特点。
Suspended stripline (SSL) provides a transmission line medium featuring many advantages, but due to the effective permittivity being close to unity, distributed elements are usually bulky. This letter introduces a novel SSL resonator, which is both compact and low loss. For that purpose, cuboid shaped bricks of metal are incorporated into the SSL channel in the vicinity of the open-circuited side of the resonator. Through this capacitive loading, the area occupied by the resonator can be reduced by a factor of about 5, yet maintaining a high quality factor. The feasibility of this new resonator type is demonstrated with an example bandpass filter at 670 MHz center frequency showing both compact size and low insertion loss.
