I am trying to create an Hybrid Metasurface Antenna Array. My S11 and farfield pattern did not come out as desired. I know this problem is due to my feed network not being precisely correct. My feed system consists of 3 wilkinson power dividers that are not symmetrical. Predicting the phase difference between the paths are very hard. How can I optimize for S11<-10db for frequency range 4.2GHz-6.2GHz? I have also attached my CST file and the antenna design article I am trying to replicate. Any help will be appreciated.
