Hello Friends,
I have been working on receiving antenna for a RFID project. Antenna is about 10 meters and am feeding it at one end to reduce the phase cancellation effect. I have found that this loop generates lobes and have a null point at middle. I have taken another small loop with L and C matching ( Tank Circuit) and seen the effect of it. That cancelled out the null point and was working fine.
Want to know why this happened? Did i increase the magnetic field strength by placing a tank circuit?
Information really appreciated.
Regards
Nanda
