Abstract
In recent years, devices with electromagnetic emission got extensive use in air-to-ground missiles (especially, the lightweight missiles), such as telemetry, altimeter and satellite positioning system. Meanwhile, for air-to-ground missiles, demand of a smaller and more compact configuration leads to a worse electromagnetic environment for antennas of these devices. Some unexpected electromagnetic self-compatibility problems occur, which might significantly affect the performance of the missiles. It is necessary to estimate the coupling condition of antennas in missiles designing progress, and evaluate the self-compatibility situation. In this paper, a simulation model based on finite integration technique is presented. The model comprises an inverted-F antenna and four microstrip antennas. Hexahedron mesh generation is also discussed. The results of the model showed that coupling parameters between adjacent microstrip antennas are much higher the other S parameters, which is up to about -30 dB. A microwave filter is needed for the antenna to ensure the coupling power is lower than blocking power.
