摘要
采用2个不同形状的谐振器和4条高低阻抗传输线作为抑制单元，实现了宽阻带、体积小的平面低通滤波器。所提出的滤波器被发现可以去除多达七次谐波。分别研究了各谐振腔对设计的影响。该滤波器的截止频率为2.57 GHz，其物理尺寸为14.6 mm × 9.6 mm。选择性为92.5 dB/GHz。在2.78 GHz到20 GHz范围内，测量到18 dB衰减水平的阻带。仿真结果与实测结果进行了验证，两者吻合良好。
Compact Microstrip Lowpass Filter with High Harmonic Suppression
A planar lowpass filter designed using two resonators of different shape and four high-low impedance transmission lines being used as suppressing cells is realized with wide stopband and compact size. The proposed filter is found to remove up to seventh harmonics. The influence of each resonator on the design is studied separately. The cutoff frequency of the proposed filter is 2.57 GHz and its physical size is 14.6 mm x 9.6 mm. The selectivity is 92.5 dB/GHz. The measured stopband at 18 dB attenuation level is observed from 2.78 GHz to 20 GHz. Simulated results are validated with the measurement results and a good matching is observed between them.
