1 Introduction
For antenna dimensioning a network analyzer is normally needed. This approach shall show how to verify your antenna by use of “simple” oscilloscope equipment and in a second step by use of an active oscilloscope probe.
2 Approach by Use of Standard Oscilloscope
Measurement Equipment: Oscilloscope with a bandwidth of >50MHz e.g. MSO6032A Agilent Technologies 300MHz 2GSa/s used for this measurements Standard Oscilloscope Probe e.g. Agilent Technologies 10073C 1Mohm, 12pF used for this measurements Low Capacitance Oscillator Probe e.g. Agilent Technologies 1144A Active Probe 1Mohm, 2pF used for this measurements Some Card (Tag) e.g. Mifare UL, Mifare Standard 1k Software Tool which swi
