Radio Basics for RFID

Keywords:RFID  electromagnetic waves  signal voltage  power 

This article is part of a book providing the basics on RF in RFID applications. It gives an introduction to electromagnetic waves, signal voltage, and power. An excerpt:

For an antenna to work, it should be apparent that something has to change: radiation is the result of the transient failure of delayed signals to cancel each other. In order to create a continuous signal, currents flowing on an antenna must continuously change, without actually getting anywhere: that is, currents and charges are usually periodic functions of time, alternately increasing and decreasing but returning to the same state again and again after the same interval.
