I am in the process of having a patch antenna manufactured through a PCB process. The antenna is fed by means of a coaxial cable. I guess that the manufacturer will place the holes for the feed, and it will be my job to connect the coaxial cable. Is that right?

My questions are:
1) What holes/vias should I tell the manufacturer to put in the manufactured patch?
2) How will I then be able to connect the coaxial cable and the patch?

Thank you!
 

You need to specify a via/hole for the coaxial inner conductor.
The simplest way to connect the coaxial connector is just by soldering the outer conductor to the ground plane and solder the inner conductor to the upper patch.

By the way, remember to empty a circle on the ground plane of the size of the coaxial dielectric, to avoid shortcircuits.

Thank you very much.
So, I have to tell the manufacturer to:
a) empty a circle on the ground plane with a radius equal to the radius of the coaxial cable's dielectric
b) drill a hole from the ground plane to the patch with a radius equal to the radius of the coaxial cable's inner conductor

Is that right? Please correct me if I'm wrong..

And could you please tell me how I can solder the outer conductor to the ground plane and solder the inner conductor to the upper patch? (since I'm all new to these things, I don't know the meaning of soldering)
 

Many thanks

And one last question..could you please tell me how I can solder the outer conductor to the ground plane and the inner conductor to the upper patch?
Is it me I have to do that? Or should I tell the manufacturer?
