Build Your Own Patch Antenna for Your Next PCB
Patch antennas are one of the simplest to design and they offer a simple polarized emission solution, especially at high frequencies. They can also be probe-fed, which is something you might find in an external patch antenna module connected via a coaxial probe. To design a patch antenna, only a few simple formulas are required, and it's possible to design probe-feeding into the antenna to operate as an external module.
