Design and Implementation of the Ka Band Parallel Coupled Microstrip Line Filter

平行耦合微带线滤波器是一种在微波电路中广泛应用的带通滤波器。设计一种应用于Ka频段的平行耦合微带线滤波器。为了保证滤波器的性能,采用HFSS仿真和奇偶模阻抗原理相结合的方法,仿真结果和实测表明,该滤波器的指标均达到预期要求。

The parallel coupled microstrip line filter is a band-pass filter which is one of the most widely used in the microwave circuit. Designs a parallel coupled microstrip line filter that is used in Ka frequency band. In order to ensure the design of the filter performance, this paper uses the method of the HFSS simulation and odd-even mode impedance principle. The simulation and practical test show that the filter performance indexes meet the expected requirements.
