I am new to designing antenna. I have the task of desingning a printe antenna that will have differential inputs for tx and rx(two spearate antenna) for Zigbee design (2.4GHz). I have several books from bancrfoft and also balanis.
The design now has a balun to convert osingle ended 50:200 ohm and then out to a invert F antenna, but we need to get rid of balun since it is pricey. Is there such thing as a differential antenna?? And would that be based on a dipole type, just curious if anyone has had to deal with a differential antenna.
