I tried to tune a bluetooth antenna and found that with series inductor, it manage to shift to the horizontal line of the smith chart. It just need another 130ohm shunt resistance to horizontally move to the center of 50 ohm impedance.
Usually the matching involves inductors and capacitors, but I had not tried resistor before. My question is whether adding a shunt resistance is recommended and will it degrade radiated power? A good or a bad move ?
thanks!
