From my small experience in filter, in the first you must Choose the substrate and then depending on dielectric constant and designing equations in chapter 3 (paper 148) from "pozer " you can design feed line.
After that you can calculate the dimensions of your antenna depending on Antenna frequency.
Thank you very much for your response. If there is one resonant frequency then the antenna dimensions can be calculated by using rectangular patch antenna formulas.
But here, I want to design a UWB printed monopole antenna. So, for this case which resonant frequency I have to choose??
