Sorry, I don't know any more about the antenna than you do, and
hopefully less (since it sounds like you're intending to make use of
it). I suggest you contact the vendor for application help. Most
manufacturers are glad to provide it.

Thanks for your reply. what about this patch antenna
http://rocky.digikey.com/WebLib/Toko...K1575MS50T.pdf
it has a feed pin at the center, the ground is the whole area around
the pin , they say it has an adhesive tape for ease in mounting to the
ground plane , is this adhesive tape a good conductor so that it
connects the antenna ground to the circuit's ground or what? so,in the
pcb design should i make a rectangular copper area under this antenna
connected to the ground?
