WiFi anti static paint
(OP)
Hi,
Does anyone know about the anti-static paint,which can be used for 2.4 GHz with resistivity of 1 G ohms square and can be applied on antennas ? Please help me if u can.

RE: WiFi anti static paint
Now, if you are talking about the enclosure over the antenna, I suggest you google for ESD paints or Anti-static paints.
RE: WiFi anti static paint
I need something which can discharge the staitc chrarge on the surface of antennas without generating sparks or effect of radiation pattern of the antenna.
RE: WiFi anti static paint
The outer surface of all my WiFi antennas are insulating, and there is no exposed antenna connection at all.

I assume you are buying an off-the-shelf antenna of some kind. You can get anti-static plastic sheets and films. I would suggest in you application, you contact a thermoform company, and have them thermoform a plastic sheet with the proper properties which you can apply over the antenna you have.
On a side note, a quick check of McMaster-Carr (mechanical/tool/materials distributor) showed they had Polyethlyene UHMW in anti-static dissipative film 0.005", 0.010", 0.020" thick part numbers 8327K11, 12, 13 , as well as thicker in thicker sheets. I just used a 3/4" thick material for a ESD production fixture, but I don't have data on the Ohms/square of this plastic. Any color you want as long as it's black.

Seems to me, such a possibility would mean death to the transceiver circuits attached to the antenna proper.

Not to seem rude, but from who or from where did you get your requirement?
I thought anti-static mats use a 500 kohm resistor to ground, but that's only after a large charge in a human is developed and he/she touches the anti static mat. Maybe your requirement comes from anti static mats??
If you are considering normal static buildup on radomes then the 300 ohm per square would be used.

RE: WiFi anti static paint
Need anti- static material just to get rid of static charge on the antenna surface.

The only thing to watch out for would be to make sure that the pointy end doesn't poke out someone's eye.
