i am trying to simulate a circularly polarized array as shown in figure. i need to feed each antenna element with a different phase. to do that i split the feed network fro mthe antenna as shown in the zoom-in where the lower port (11) is the output of the feed network and port (12) is the input of the antenna. Through schematic, i connect the output of the feed network to the input of the antenna through a phase shifter as shown in figure 3. but the simulation did not work as expected. for example S11,1 & S12,1 are shown to have big amplitude power while they are the input and output of an ideal phase shifter.
i need help to know what needs to be changed in my simulation setup to meet the goal of the simulation.
I appreciate your help.
regards
