What’s the thickness of FR4 substrate that one should take when designing a micro-strip antenna with an HFSS tool?

I am designing a micro-strip antenna with an HFSS toll, what's the thickness of FR4 substrate that one should take ?

As I recall, most FR4 stock is .062in thick. The thickness of the stock is not quite as important as to your specification of the stock.

One can have a PCB house plate copper onto the standard board stock to your specs, which might be more useful in your micro-strip design parameter selection.

To be fair, hoewel, I am unfamiliar with the software tool you mentioned. I had to do the design the hard way and tweak as necessary.

Remark:

  • If the board is single-sided, then the above is true. The copper thickness is more important than the substrate itself.
  • If one is using a two-sided, or multilayered design, the thickness of the stock is one more difficulty to be solved in designing your micro-strip elements., especially the distance to a ground plane.

Is solder mask a valid electrical insulator?

There is a copper pour over the entire top of the my PCB, which is part of GND net. It turns out that the surface mounted 1W LEDs I’m going to use have the heat slug connected internally to the LED’s +ve terminal. Can I rely on the solder mask to insulate the +ve voltage (~3V ish) from GND? Long term?
