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, though, 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.

What Others Are Asking

How can I connect my small PCB with sensor to the bigger PCB?

My small PCB is mounting a very sensitive fragile sensor on the top surface that has to be wire bonded to the PCB, so I am trying to design a smaller PCB that can be surface mounted to the bigger PCB. How can I get some kind of thin footprint for interconnecting the two PCB boards?

Can I use LEDs without PCB?

I recently purchased LEDs on ebay that were supposed to come attached to star PCB (as a heat sink). The items I received are just the LEDs (no PCB). They are listed as 3W LEDs, with a forward voltage of 3.0-3.4V, and current at 700mA.Will I damage/destroy the LEDs if I use them without a heat sink? If not, what is the best way to mount these to preserve their life during operation?
