I've designed IFA antenna in Altium as described in DN007 and created a balun circuit from the schematic design of CC2500EM Reference Design (swrr016a). I'm very new to RF designs, as I could understand from application notes and forum posts; this design shall work with the right thickness of PCB. My PCB will be a 2 layer PCB and I'm planning to use only the top layer to be the PCB antenna, for maximum range shall I use layer stacking (use both of the PCB layers?) and shall I use a 50 Ohm transmission line on the connection of antenna after connected to balun circuit?
Thanks in advance,
