what i understand is that you need to model a coaxial to microstrip trnasition ?

Thank you so much Qian Xu , Anuraag Misra 

Complete model of SMA is not the best option; because it is complicated to draw.

Just place the center of SMA as a PEC cylinder with radius 0.65 mm.

Place a teflon cylindrical shell (er = 2.1 and tan_delta = 0.001) with radius 2 mm (0.65 to 2.65 mm).

Place a PEC cylindrical shield with radius 0.5 mm (2.65 to 3.15 mm).

The length of this SMA must be larger than 5 mm

Thanks dear Ahmed

I have designed sma connector in hfss but not getting good s21 value... can anyone having the model of sma connector ..

Hello,

Try de modify the length and the diameter of this connector,you have to play with these parameters ,and the best think that you can do is to model an SMA as the orignal version that you can find it in several websites companies for microwaves components.

Dear Qian Xu

can u send me ur HFSS file for ur SMA connector at the following email ID:

Here is the SMA connector modeled in HFSS.

Can you share an HFSS project file in which this connector is used to feed a microstripline? Not perpendicular but as an end launcher

thank you
