simulate coaxial cable

Hi , I am new in CST and I don’t know how to simulate a 50 ohms coaxial cable (174u)
Does anyone has any tutorial on coaxial cable design on CST

edaboard cst coaxial cable

first you calculate the inner , outer diameter and dielectric constant of the dielctric material from the well established formula

**broken link removed**

after that first you define the outer cylinder of the desired outer diameter with the know dieletric properties after that create another cylinder of inner diameter of PEC material and then insert it in the previous one and then assign the port.

another question

I need to take account the shield and the jacket?

how to simulate a cable

hai herewith i have attached the datasheet for 174u coax cable u need to simulate the cable with shielding, jacket is not needed. define the shield as a ground

see the picture and put the waveport like that
