Thank you for the explanations. Another fact which has never been answered in any Antenna books is that in coaxial feeding when you connect the central conductor of the cable to the patch, this part of the wire separated from the coax and passes through the dielectric to the patch. This part of the cable between the coax and the patch is no longer continuation of the coax, so what is the impedanace of this small section? Almost everybody ignored this section and has never discussed it.

An "Aha ha" moment for me in the understanding of inset-feed patch antenna.
Nice video keep the progress
