I am trying to understand how range of communication between RFID reader and tag is related to frequency and power.
So if I increase frequency, the range will be shorter or larger? why? (I need to understand basic mechanism)
I have an RFID reader. This one is having a range of only 5-10 cm. I want to increase its range to say 1 meter. I understand that if I can increase output power I can transfer energy to larger distance, so I can energize the tag kept at larger distance. So can I increase the range by amplifying the signals and possibly connecting it with a different antenna which can send the signals to a larger distance? If yes how?
