[ANT] Can I make the antenna “snake-like” similar to the one on the bluetooth module ? I’m not sure yet if it fits even like this.

A snake like antenna at 868 MHz should be 8.2 cm long for optimum performance. If it is shorter the efficiency is reduced, but still doable by adding matching components. In designs of antennas, always remember to include a PI matching network circuit. This will give you a degree of freedom for tuning it properly.
