本文提出了一种超小型阻带微带线。频率间隙是由一个阵列互补开口环谐振器（CSRRs）-一个概念prohere第一次-蚀刻在接地平面上。这种行为被解释为由于在谐振附近的负有效介电常数的存在。所得到的器件产生具有锐截止的深抑制频带，以及具有非常低的损耗和良好匹配的通带。由于CSRs的亚λ操作，器件的电气尺寸非常小。
In this letter a super-compact stopband microstrip is proposed. The frequency gap is produced by an array complementary split ring resonators (CSRRs)-a concept prohere for the first time-etched on the ground plane. This behaviour is interpreted as due to the presence of a negative effective permittivity in the vicinity of resonance. The resulting device produces a deep rejection frequency band with sharp cutoff, and a pass band that exhibits very low losses and good matching. Due to the sub-lambda operation of CSRRs, the electrical size of the device is very small.
