微屏蔽三线对称结构带通滤波器设计
Design of a passband filter based on three symmetric microshield transmission lines
摘要
Abstract
The film supported cavity microshield transmission line is analyzed and its physical structure is given out. In order to verify the superiority of microshield transmission line in millimeter wave application, parallel-coupled microstrip line method is adopted to design a 4th order Chebyshev filter with the three-symmetrical-line structure. The proposed microshield cavity structure is simulated with HFSS, achieving a broadband filter with center frequency of 35GHz, bandwidth 15GHz, band insertion loss below 0.5dB and band rejection>40dB@53GHz. The device has a size of 8.24mm×1.5mm×0.65mm. This design provides a possible method for implementing filters based on plain transmission line in millimeter band.关键词
