Claim 8:
9. The method of claim 8, wherein detecting an incident wave power and a reflected wave power when the antenna device is in operation, and determining a real-time standing wave ratio at a position where the antenna device locates comprises:
receiving an incident wave power and a reflected wave power when the antenna device is in operation;
attenuating the received incident wave power and reflected wave power to obtain an attenuated incident wave signal and a reflected wave signal;
detecting the attenuated incident wave signal and the reflected wave signal and outputting output detection voltages including a forward detection output voltage and a reverse detection output voltage; and
performing subtraction on the forward detection output voltage and the reverse detection output voltage to obtain a difference between the forward detection output voltage and the reverse detection output voltage; and
determining, according to the difference, the real-time standing wave ratio according to a function relationship between the difference and a reflection coefficient and a function relationship between the reflection coefficient and the standing wave ratio.
