Disclosed in the present invention are an electromagnetic wave detection device and a method thereof. The present invention detects electromagnetic waves across a broadband and enables follow-up measures to be taken accordingly. The present invention introduces a subminiature dipole antenna and uses a diode as a detector in order to efficiently detect electromagnetic waves sensed by the antenna. In addition, in order to process the detected signal, a transmission line connected to a central processing unit is designed to have high resistance to distribute current properly and thus to not compromise the efficiency of transmitting the detected signal. Furthermore, in the present invention, the actually-detected electromagnetic signal is not directly determined as a measurement value. Instead, a compensation value is applied to the actually-detected value and the calculated result value is determined as an electromagnetic wave detection value so that the electromagnetic detection amount can be accurately determined.
