feko antenna array

Hello!

I am doing a science fair project and I want to modelize a base station antenna that the radiations would be less concentrated at ground level. I am using Feko (licence with no limitation of meshes), and because I am a beginner, I would need your help. I am looking for a model file of a rectangular microstrip patch antenna array with corporate or serie feed, operating frequency of about 1900 MHz, and preferably 4 elements.

Thank you very much for your help!

Any other base station model would also work.
