Lumped port joining ansoft HFSS

How can I join lumped ports to give same excitation to an array of four patch elements on one substrate. Because if I assign separate lumped ports to each element, the gain it gives is based upon only one element and this is also true for other parameters.

Can we relate one port to another in terms of amplitude and phase.??
Thanks

i think u have to design a feed network for the 4 patch elements, u will have only one excitation port that feeds the a elements.

thanks, i got solution from other topic it is. hfss>fields>editsources, and u can assign scale factors to any sources to make them active

hi all, if there is some one can help me, I need example in HFSS to design Double ridge Horn Antenne,
