In tuning an antenna, there are multiple possible topologies that will take it to the middle of the smith chart.
Some differences that I can see between them are:
- Component ESR (losses).
- Effect of component tolerances.
- Resulting antenna bandwidth.
For example:
Alternative 1 "LpCs"
Alternative 2 "LpLs"
Alternative 3 "LsCp"
Which one would you choose and why?
