Antenna Layout Optimization Method Based on MATLAB and CST Interactive Simulation

Due to the limited space of the carrier, the multi-antenna system on the carrier is prone to electromagnetic interference. Most of the researchers used genetic algorithms to optimize the antenna layout. On this basis, this paper proposes a method of interactive simulation of MATLAB and electromagnetic simulation software CST. Firstly, the position information of the antenna and the carrier platform is initialized in MATLAB, and then the program of the genetic algorithm is run, and the layout scheme of each generation is automatically transmitted to the CST through the ActiveX. The CST solves the antenna coupling degree and automatically returns it to MATLAB as the fitness value of the scheme. After dozens of generations of genetic algorithms, a better layout scheme can be found. Compared with the previous optimization methods, the method of this paper does not need to build complex electromagnetic numerical calculation model, and it has strong operability and high degree of visualization. Therefore, it has certain reference for the layout optimization of multi-antenna systems of other carriers.
