摘要

本文提出了一种具有超宽带通带的紧凑型微带带通滤波器。该滤波器是基于传输线带通滤波器设计的，该滤波器具有三个短路stub，由两个非冗余单元元件分隔。每个均匀的非冗余单元元素被一个低通滤波器取代，以缩小滤波器的物理尺寸，并拒绝通带的第二个不需要的杂散谐波。该滤波器设计成功，并通过全波仿真和实验验证了设计的正确性。理论、电磁模拟和测量结果之间的一致性非常好。该滤波器表现出良好的性能，在中频下插入损耗小于0.6 dB。

Compact Ultra-wideband (UWB) bandpass filter with wideband harmonic suppression

A compact microstrip bandpass filter with Ultra-wideband passband is presented in this paper. The filter is designed based on a transmission line bandpass filter with three short-circuited stubs separated by two non-redundant unit elements. Each of the uniform non-redundant unit elements is replaced by a lowpass filter to shrink the physical size of the filter and to reject the second unwanted spurious harmonic of the passband. The filter is successfully designed and the design is verified by full-wave EM-simulation and the experiment. Excellent agreement between theoretical, EM-simulated, and measured results is attained. The filter exhibits a good performance with very low insertion loss of less than 0.6 dB at the mid-band frequency.
