Hi all,
For a product which will communicate over NB-IoT at around 800MHz we are currently busy with the design of the PCB. For best performance we would like to have a ground plane of at least 1/4 of the length wave which corresponds to roughly 90mm. Our PCB is due to mechanical constraints maximum 80mm.
Is there a way to determine roughly the performancy penalty we will receive for this smaller ground plane?
Also the PCB will have a right angle SMA connector which will connect to the antenna. Due to the fact this SMA connector is connected to the ground plane and is extending the physical length of the pcb. Could we count this SMA connector as part of the PCB and so as part of the ground plane?
Thanks for thinking with us.
