       When HFSS Needs Port Calibration (deembedding)           


When HFSS Needs Port Calibration (deembedding)

• If regular (perfect) ports are used, HFSS does not need any port calibration

• If inperfect ports are used (internal lumped port), HFSS also needs some part calibration (deembedding)

 

Deembedding extension/transition effects

 

Deembedded to the discontinuity

 

Deembedding extension/transition Z matrix method (simplified approximation)

Impedance matrix Z* is meaured/simulated. Where Z1 and Z2 are known, calculate/deembed Z matrix
