Edge Coupled Filter Design

Tags: HFSS, Designer, Bandpass, Microstrip, Microwave Engineering


The design, optimization, fabrication, and measurement of an edge coupled Bandpass filter realized in Microstrip technology is presented. The design process begins with written filter requirements and finishes with a fabricated circuit. The presented process includes the estimation of filter parameters using analytical formulas, the simulation of ideal and Microstrip transmission line models in a circuit simulator, the simulation of Microstrip models in a full wave 3D simulator, and the fabrication of the final design using a rapid prototype milling machine. An extensive comparison of the response obtained from simulation phases and the final fabricated design is presented. The author’s reflections regarding such inaccuracies present between the various simulators and the fabricated results are included.
