    Ground plane, patch, feedline dimesnion and the impedance matching

    I am design a micro strip patch antenna for UWB application (3.1-10.6GHz) in CST. The substrate is Rogers RT 5880 and the feedline, patch and ground plane is Copper (Annealed). The feedline is Micro Line Feed. the is result for S-parameter is accepted but the z-matrix(impedance) is around...
