Crosstalk Reduction in Microstrip Lines | FEKO Simulation
0Crosstalk is a serious issue in high-speed microwave and VLSI circuits, especially in multi-line microstrip layouts. In this video, we analyze how to reduce crosstalk noise using three different methods:
✅ 3W Rule
✅ Via Hole Fences with Guard Trace
✅ NEW: Rectangular Metal Trace
Using FEKO 5.5 simulations, this study shows that replacing via fences with a rectangular trace can reduce crosstalk by 7 dB, improving performance by 1 dB compared to traditional via fencing. This is essential for modern electronic products requiring small form factors, high speed, and low voltage supply.

Rectangular Trace Application in the Reduction of the Crosstalk of a Coupled Microstrip Line
Layman's Abstract :
This study looks at a common problem in electronics called crosstalk, which happens when signals from one wire interfere with another wire on a circuit board. This is a big deal in today’s tiny, high-speed electronics like smartphones and computers. Crosstalk can mess up signals and lower performance. The researchers tested three different ways to reduce this interference between two microstrip lines (types of wires used in circuit boards). The newest method they tested uses a rectangular metal strip between the wires, which turned out to be the most effective — reducing the interference better than the other two traditional methods. They used a simulation program called FEKO to test this. The results show that using a rectangular trace is a better way to make circuits cleaner and more reliable.
