Hello
I simulated a loop antenna working at 2.2 GHz, in HFSS using lumped port. I want to make this antenna and it has a input impedance equal to 200+j0 at its resonance freq.
shall I use a balun and if yes can you help me what kind of balun should be used?
For proper differential application,balun in needed between your loop antenna and transmitter,of course the balun may be deleted only when your transmitter has diff.outputs.
The SMD balun is good choice in our band, impedance matching may be needed.
