A method for measuring a voltage standing wave ratio by a measuring system for a voltage standing wave ratio includes the steps of: receiving a main signal to be output through an antenna, and a return signal which is a portion of the main signal being returned; extracting a first reference signal from the main signal to obtain a power size of the first reference signal, and extracting a second reference signal from the return signal to obtain a power size of the second reference signal; and comparing the power size of the first reference signal with the power size of the second reference signal to calculate a difference value, and then calculating a voltage standing wave ratio based on the difference value. |
