Design parameters for 2.4GHz and 915MHz PIFAs
I am a research intern in Australia, my task is to design 2 PIFAs which operate at 2.4GHz and 915MHz. I've come up with over 10 designs for both on CST/FEKO/MATLAB but none are satisfactory. Can you please provide me the design parameters for both, I could really use some help.

So there are very specific antenna design requirements that you need to detail out before choosing a design. Let's start with some of them :
* Omni-directional or directional ? (you mentioned PIFA which is typically omni-directional)
* Co-planar / Planar or 3-Dimensional ?
* Separate or Combined antennas ?
* Frequency Bandwidth ? (for each frequency)
* Minimum Gain for each antenna band ?
* Dielectric Materials (limited or unlimited) ?
* Metals (limited or unlimited) ?
