[CST DS] Six ports Combination Using Couplers

Hello!

I work on an Antenna design with CST Microwave Studio. The Antenna has 6 ports that have to be combined 2 by 2.

Port 5 and 6 have a phase sift of 180. 1 and 2 quadrature sift. Same for 3 and 4.

I tried to used The block diagram on CST to add the couplers but can't get the s-parameters.

I am not sure that connecting the couplers this way will work. Could anybody help me out?

Thanks ^^
