3–3.5 GHz Rectangular Patch Antenna

I need a complete CST Studio Suite model of a rectangular microstrip patch antenna that operates reliably across 3000 – 3500 MHz. Designed antenna would be used in an array to feed angle of arrival (AoA) direction finding cuircit on a parallel seperate board through u.fL connector cable...
