Abstract :
This paper revisits the differential probe method to measure the input impedance of balanced antennas. The differential probe method has been described briefly and it has been applied for various types of antennas. Measurement and simulation results have been provided for center-fed and offset-fed dipoles, electrically small antennas, and RFID tags.
