CC2651R3: ant

To answer your previous question about reducing F to 10mm, the answer is a bit nuanced. The dimension F is more about the availability of ground plane the antenna needs to maintain sufficient bandwidth and frequency response meaning the missing 3mm x [number of layers] must be compensated elsewhere otherwise bandwidth will degrade and frequency response will shift. While we do not recommend changing any dimensions, it is possible to tune the frequency response back to 2.44GHz but also understand it is a risk and will need thorough modeling, simulations, and lab measurements.
