Hello.
I've recently started experimenting with antennas and I'm confused about how to solder the coax to an antenna.
An example, here is a picture of a microstrip antenna with a coax feed
I see the shield of the coax is connected to the ground plane and the center pin is connected to the radiating patch. But how is the circuit completed? there is no apparent path from the radiating patch to the ground plane for current to return.
If I were to use a coax cable for a monopole antenna, how would I connect it? Where/How would I make a ground plane from a straight wire?
I appreciate your help.
