I also recommend the stylus antenna with respect to the coil antenna possibly connecting 3 stylus antennas together.

Most of the time I'm not in Italy and I have not kept the design of the pcb, very often drawing the tracks directly on the pcb. I want to remind you that the sensor stage is made up of a high gain amplifier that can easily oscillate, so it may be best to separate this stage from that of the CD4046 if you choose this solution.
