Must Ground Plane Connect Directly Under Antenna?
« on: December 09, 2024, 09:10:29 pm »
In this proximity coupled antenna, is it necessary to solder a ground connection directly beneath the antenna? Or can the ground plane be connected to ground point elsewhere on the ground plane, far away from the antenna?

Assume the patch substrate and ground plane are several wavelengths larger than the patch.

If I were to feed this antenna with e.g. a coax line, I'd solder its outer shield to the ground plane right where the stripline starts at the edge of the substrate..
