Will anti-static plastic interfere with GSM/GPS signal
Will anti-static plastic interfere with GSM/GPS signal
(OP)
Hi, i am a novice trying to design a casing for GPS/GSM enabled key chain. I have two questions for which i was hoping some one could help me with.
First one is. Is it really nescassary to make a plastic casing for electronics anti-static?
Second one: Does the anti-static grain interfere with the reception of GSM or GPS signal? Maybe like a faraday's cage?
If some one could answer these i would be very grateful!
Thanks very much in advance!

If you look at the impedance of space (the medium that radio waves travel in) and the impedance of anti-static plastic, you will see 377 ohms for space and probably megohms for anti-static plastic. That alone indicates that you will not have any problems.
But stand by for someone that has actually tried. I haven't.

You need the cup of water to ensure that there is something in the microwave that is absorbing the energy; otherwise some microwaves will shut off if they don't sense the energy being absorbed and you'll get a false reading.
I've always figured if I stay about 0.1" away from a metal case that the gap is wide enough to stop an 8KV spark (the IEC standard). I believe that logic should apply for plastic too.
