Antenna selection and layout for the Teseo-Liv3r GPS

NataliaNPL · ‎2024-12-19

Hello everyone!

I'm a beginner in hardware design and I'm trying to design a simple smartwatch. For the GPS function I decided to use the Teseo-Liv3r. The fact is that in the user manual they indicate several types of antenna, in this case I have selected one of the recommended ones, the ANT1818B00BT1516S.

My questions are:
+ Section 8 is the recommended layout, it tells me to use a 50 ohm line, how can I calculate the track thickness correctly?
+ On the other hand, section 9.1.2 shows an example layout, does it maintain a specific distance between tracks?
+ I understand that surrounding the track path is to ensure the RF path, should I take into account that tracks pass under the path in other layers? Or, if there is a ground plane, would it not affect it?

Finally, do you think I should use another type of antenna for my design? I'm looking for something small, but I'm not sure which one to choose.

Thank you very much in advance
