4 x 4 patch feed network help

Hi,
I am looking for help with a 4 x 4 patch feed. I have simulated single patch using 1/2 wave feed line. This gives 60 ohm impedance.
How do I combine the 4 patches do I need impedance transformers?

Has anyone any examples or tutorials showing the feeding a 4x4?

Thanks for help

Study the techniques for power combiners and dividers.

thanks for response, Can you recommend any practical guide to power dividers/combiners. Any searches I have done give very liitle details or practical examples.
