hello all, im new to the rf design, and im designing coaxial feed trianglar antenna , and i have done simulation can any one verify my results and tell how to generate gerber file in cst studio.

 

I am not a specialist in 6 GHz designs, but here are some general comments.

• Your design seems to have a sharp notch at the matching frequency of 6 GHz. Check your required bandwidth vs. your matching bandwidth.
• Sharp notches (high Q factor) are usually susceptible to component tolerances. You should do simulations with max/min tolerances of your used components PLUS mechanical tolerances of your antenna and matching stripline, don't forget PCB thickness and variations in epsilon_r of your dielectric.
• Don't take simulation results as the real truth. Especially the results of 3D field solvers like CST and others may vary with your chosen simulation setup and model structure. Expect some differences between simulation and real life (prototype)
• I am not familiar with CST, but with another powerful simulation tool. But I think there will be no direct Gerber export. Usually these tools have the possibility to export to a transfer file format for professional layout tools. With these layout tools you have to add other layers that are relevant for your layout like solder paste, solder resist ...

Good luck with your design

 

thanks for your responce.

 

thanks for your responce.

if you dont mind can you tell me by cutting the 4 ground leads from the edge mount sma connector can i use that for caoxial feeding ( back mount sma connector) thanks.

 

I don't know anything about your design. So I can't tell you whether it is possible or not. Maybe you can do some simulation to see the electrical effects. You should ask your manufacturer, whether mounting of such a modified connector is possible.

You are using a professional simulation tool, priced in the 5-digit-$ region. So I assume this is not a DIY/hobby project but a commercial one. As other members in this forum mentioned, for this case commercial support rates will apply.
