Microstripline filters are essential components in RF and microwave circuits, offering a compact and efficient way to shape frequency response. In this post, we’ll walk through the complete process of designing, simulating, fabricating, and testing a microstripline filter. Starting with electromagnetic simulations in Ansys HFSS, we’ll validate the design before exporting it to KiCad for PCB...
I’ve always wanted to model the effects of a choke balun on a balanced dipole antenna fed by an unbalanced coaxial feed line. In particular, I wanted to model the antenna and feed system using EM software in order to visualize the electric field and current along the conductors in the system. Essentially, I wanted to prove to myself that the concepts that I’ve seen in literature and...
