Antenna for a Nordic Semiconductor nRF8001 Bluetooth Module

I found a reference design here (see the image below). I’m guessing the antenna is that trace around C5 and C6. This is the same design in the datasheet. I also found a document on antenna tuning with lots of equations and the need for some expensive equipment. [image] Adafruit also has a design with a completely different antenna. I may just copy the Nordic’s design, spin a PCB, and give it a try. But I’m not really sure how I would tests it’s efficiency.

Gerber to Footprint

Made the video this morning, hopefully it helps clear things up: [KiCad 3.0 - Making A PCB Antenna in KiCad]

Filled area from imported DXF

one option is to import your dxf shape in pcb footprint editor and export it as a module .kicad_mod then open it in text editor and collect the point modifying it from fp_line / fp_arc in polygon to see how a polygon is done in kicad just create a new board and place a fill zone, save the board and open it in text editor then convert your point to the fill zone structure and assign it’s net to the net node you need if everything went fine if you re-open your board you will have a fill zone w…
