Multi coaxial cable connection

Hello
I am working on an equilateral triangular patch antenna, and i have finished the design and the simulation using HFSS, and the result were impressive. The patch is excited using two in-phase coaxial cable. the question is how i can hook these cables together.

Best regards

i guess that what is needed is a way in which only one coax-cable is needed and the inner of this cable is split into two conductors located at the position of the two coax-cables inner

hey guys i have designed the required coax with it's inner split. the problem is when i run the design i got nothing, a validation check is made and everything is correct. when it start simulate it run 2 passes and solve at 3 or 4 frequencies. i set the number of passes to 8 and the maximum delta to 0.002. could you please help me
