Analysis Of Interference Among The Vehicular Multiple Antennae

Moment method is used for the analysis of interference among the vehicular multiple antennae in this paper. The multiple antennae system is equivalent to a microwave network, then the admittance matrix of the network can be obtained. Using the admittance matrix, we can analyze the characteristic of coupling between two antennae and the near field of the antennae by the MOM. The module of the car is the key of this program, so the way of modeling automatically by a computer is studied for speediness and directness. A real car is used as the module with abstracting and simplifying. In addition, a software interface is designed for the computing program so that the modeling becomes visual and commutative.One of the engineering problems is presented with the complex modules and great efforts. Harmonic interference among antennae is emphasized and the level of the highest and real coupling is computed. We give the real coupling level. It is proved by analyzing that the method is exactitude in theory and precise in solution and can be used as a guidance of equipment and collocation of the vehicular multiple antennae.
