Stripline vs Microstrip
Shielding
Better EMI immunity with two reference planes
Crosstalk
Lower crosstalk than microstrip
Propagation
Slower due to full Er (not effective Er)
Design Tips
- Use symmetric stripline when possible for best performance
- Ideal for high-speed signals requiring shielding
- Requires via transitions for component connection
