14.3 GHz Printed Dipol Antenna Design, can you help?

Hi, I need to design a printed dipol antenna working at 14.3 GHz in CST MWS. I searched, but couldn't find a design at this frequency. Can anybody help me?

What is exactly the problem? Finding a finished design at exactly your frequency or what?

What substrate are you going to use (thickness, Er)?

Yes, I need a finished design. Parameters of substrate should be (epsilonr=2.08, substrate thickness=1mm) or, (epsilonr=4.9, substrate thickness=1.6mm). Thanks for answer...

I don't think you'll have the luck to find a finished design. I suggest you to start from the scratch, simulating simple (printed) dipole structures. First without the substrate, then with it. I would also suggest you to use small Er and thin substrate than large Er and thick one because of surface modes in the substrate.

Hmm, bad luck for me. I tried to design. I changed parameters of a design working at another frequency; and I catched 14.3 GHz, but farfield pattern wasn't a dipole pattern anymore.

Thanks for answer

Attach the picture of your structure for us to see what you're simulating.
