Hi,
EDIT: Frequency is 868MHz, and physical dimensions of PCB is approx 40mm*20mm.
I am trying to make a small wireless unit were I want to change the antenna matching based on wether the unit is placed in a hand or not.
My question is based on the attached picture.
I want to change the matching by turning on or off L2 when I sense a weaker signal.
My question is:
Will the trace with the L2 inductor affect the matching when the pin is left floating?
Does anyone have experience with something similar?
Thank you very much!
