“…There are currently two main methods for obtaining the coupling degree: Measurement and numerical simulation technique. Since actual measurement of the missile system often requires a significant amount of resources, and it is difficult to solve the problem in the early engineering stages, the increasingly mature electromagnetic numerical simulation is increasingly being applied in the practical engineering analysis [4][5][6][7][8]. Therefore, in this paper, an electromagnetic simulation model of a typical missile with multi-antenna system is established to analyze the electromagnetic compatibility of multi-antenna situation.…”

Due to the compact spatial structure of missiles and the close proximity between antennas of different wireless communication device, the electromagnetic compatibility problem of multi-antenna systems is becoming increasingly prominent. To solve this problem, this paper establishes an electromagnetic simulation model comprised of missile, two inverted-F antennas, microstrip antenna and microstrip array antenna, which is based on the numerical simulation software CST. In order to evaluate the electromagnetic compatibility between antennas in the multi-antenna scenario, the S parameters representing the coupling degree between antennas are simulated and solved. The simulation results show that the coupling transmission parameter between two inverted-F antennas are much higher than other antenna pairs, which indicates the antenna coupling degree is closely associated with the distance between antennas and the structural form of the antenna. Further, a method for evaluating the electromagnetic compatibility of multi-antenna system is presented, and a calculating method for the suppression performance indexes of the antenna radio frequency filter is provided.
