Transition 1
Strip dimension shrink (W/L = cst)
Transition here ?

Transition 2
Continuous microstrip to coplanar transition
Problem: Transition 1 & 2 implies coating a PCB with an angle which might not be possible and expansive

Real world implementation
Instead of having an angle in the PCB the angle can be made via staking of layers. In PCB we can have up to 16 layers. Need to be simulated.

Transition 2 simplest implemetation

Transition 2 improvement
improvement
Field rotation
The via transition could be replaced by progressive stacking of layer for a smoother transition.

Status
• Model being put in HFSS for field simuation.• PCB card design started with the help of
Mircea.• Help given by Xioahuan (Klaus’ student)
working on the same issues.• All ideas to go from PCB to microstrip are
welcome.
