Actually I am not trying to design antennas ( 500Mhz to 1Ghz- I guess
this gives you information about what sort they are), I am trying to
buy them on a pcb or small chips that could be mounted on a PCB.

Your wavelength of interest is 3cm at a minimum...
you're trying to put them into a box smaller than
that.

How much gain should this antenna have? How
broad-banded does it have to be? How much
power does it have to handle? What kind of
polarization do I want? These are basic
questions you should answer.
