Double-Patch inspection and treatment
Inspect the procured double-patch antennas:
-
Visually (scratches, finish) -
Mechanically (dimensions, thickness)
Then proceed to the cutting treatment to separate them and repeat inspection.
No copper fill is existent on the junction of the two, so cutting carefully with something like a dremel should be safe. We need to:
- Ensure FR4 and copper layers do not separate after cutting
- Look into applying coating where the cut was made such as soldermask
