WebAntenna impedance relates the voltage to the current at the input to the antenna. This is extremely important as we will see. Let's say an antenna has an impedance of 50 ohms. This means that if a sinusoidal voltage is applied at the antenna terminals with an amplitude of 1 Volt, then the current will have an amplitude of 1/50 = 0.02 Amps. WebWir wissen, dass, wenn eine Lichtwelle (elektromagnetische Wellen) von einer starren Grenze reflektiert wird, der reflektierte Strahl eine Phasendifferenz von „Pi“ (180 Grad) erleidet.
