No its not. The lumped port have to connect the inner conductor with the two outer conductors. Eventually use a sheet of perfect E to connect the lumped port to the outer conductors

Eventually like this: https://obrazki.elektroda.pl/4794382100_1360526422.png

Hope it helped,
Mads

Another option would be to create a wave port (perpendicular to the CPW) with the integration line defined from the edges (ground) to the center conductor.

You could then verify through the 'Port Field Display', that the E-field is in the desired mode.
 

Hi Mads,

Could you please say more detailed about this lumped port? Where did you place the port and the perfect E sheet? It will be even great if you could upload your project file. Thank you very much!
