how to find the thickness of a circular disk patch antenna.. i am using a frequency of 62.5 GHz .... pls reply
 

perhaps you will need to consider the skin depth & losses on material.
 

Do you mean the thickness of copper ? It should as thin as possible. If you meant the thickness of the substrate, it should be as high as possibl ein order to get maxmium fringing/ radiation.

See Belanis chap on patch antennas.
