Chip Antenna Design for NEO-M9N

Thread Starter

I would like to develop a board with the GNSS module NEO-M9N. I would like to use a chip antenna. According to the data sheet, the impedance of 50 ohms does not have to be taken into account for the RF input signal. So I can draw a trace of any length and thickness. Or have I misunderstood something.

There are also other components and microcontrollers on my circuit board. Would a 4 layer board with 2 inner ground planes be better than a 2 layer board with GND polygons on top and bottom?

Sorry for my bad english and looking forward to answers:)
