Hello all,
I am back again after several years absent of this forum where I learned a lot and first shared my experiences with LoRa and moteinos.
This time I am working in LoRa project where one of the Lora node basically will be located at someone pocket or purse.
I read that the trace antenna is ideal for such project , desired range 0.5-0.8 miles but. I just making test comparing pcb trace vs coil antenna.
I would like to know how the capacitor and resistor the pcb trace antenna termination was choose ? I found some documents on the web and resistor value indicated is 2k .
more tests.. moteino on my pocket ;D
Not bad for such a small antenna!
The parts are part of impedance matching.
