IoT sandwich – GPS chip loop antenna on German bacon – 1

Today we tell you the ingredients you will need in order to reproduce the world’s first IoT sandwich. The sandwich is planned as a starter.  We will show you how to make the main course and the dessert later.

Ingredients for the IoT sandwich

For the PCBs

  • 9 different PCB shapes (3 different cut-out zones on 3 PCBs = 9 different PCBs)
  • 9 GPS chip loop antennas
  • 9 U.FL connectors
  • 9 capacitors
  • 9 inductors

To enclose the PCBs

  • 1 plastic enclosure
  • 1 LiPo battery
  • 1 piece of polystyrene (e.g. Styrofoam)
  • 1 piece of German bacon

For the test setup

  • 1 Vector Network Analyser (up to 4 GHz)
  • 1 U.FL to SMA coaxial cable
  • 1 balun inside of the U.FL to SMA coaxial cable
