Concentrating on the two-pin electric explosive devices (EEDs), this paper proposes a coupling model of V-type antenna according to the typical situation that the pin wire can present a certain angle. On the basis of theoretical analysis, numerical simulations are performed to obtain the different angles of antenna patterns, the changes of the reflection coefficients, and the gain of coupling current and the influence law of coupling energy, which are verified by experimental measurements. The results show that the coupling current and energy increase rapidly with the increase of the angle when the included angle between two-pin wire exceeds 60 degrees. When the temperature reaches 90 degrees, the coupling energy would increase to tens of μJ, which will bring certain safety risks. When the included angle rises to 180 degrees, the coupling energy will reach the peak. The conclusion of this paper is helpful to the environmental adaptability of high-altitude electromagnetic pulse (HEMP) for EEDs.
