A previous KiCAD designer on our team designed a Bluetooth antenna from a series of traces and, of course, a separate capacitor footprint. All traces were of a precise width and length as specified in an antenna design program to which I do not have access.
I needed to design a new board which includes this antenna. It was very difficult to move this antenna around the PCB during the design process. So I designed a footprint for a Bluetooth antenna with an accompanying output capacitor. You can drag and drop the whole thing as a single unit.
I thought this was pretty clever.
And it does everything I want, except for one thing: Since the antenna is defined as an irregular pad, the whole antenna is exposed. I don’t know whether that matters, but in the reference design the antenna region is under the solder mask.
I know how to expose regions of a footprint by defining polygons on the solder mask layer. Is it possible to go the other way, and require that certain copper regions be covered in solder mask?
EDIT: I should mention that I’m using KiCAD 5.1.5.
Thanks for your help!
