Interference Prediction And Laout Optimization Of Multiple Antennas Within A Limited Area

The radiation characteristics of antenna systems and antenna layout optimization on a platform conductor are of great significance to the electromagnetic compatibility of the entire communication system, especially for the optimal placement of antennas in finite large space has become a focus.Optimal placement of antennas can regard as a black box problem, it aims to use the least conditions to achieve the best result. To solve this problem, this paper has done some innovative works as follow:1. Put the hybrid algorithm used in optimizing the antenna array applied to optimize the antenna layout optimization, for the study of the most widely used wire antennas, take the classical electromagnetic analysis methods of MOM and MLFMM for the basic, started with simple model to prove the algorithm’s correctness and effectiveness apply it to the complex model, take the complex model to simple ones, use Simplex algorithm for local optimization, then integrated the simple ones and use GA for global optimization. With a combination of these two types of mathematical optimization algorithm, improve the efficiency and accuracy of the optimization, provide a well-established analytical methods for the layout optimization of multi-antenna in finite large space, especially for the analysis of the actual ship model, it must have reference to today’s naval operations on the electromagnetic compatibility requirements.2. From the other factor-frequency which effects the isolation between antennas for the starting, consider the optimization algorithm as a search engine, looking for the optimal system frequency and the smallest band satisfy the request of isolation between the antennas in normal working during the full-band..3. Considering the location and frequency of the antenna can be changed at the same time, Separately discuss for single-parameter optimization and multi-parameter optimization, put the layout problem of the antenna up to two-dimensional perspective, Write software and maximally solve the antenna layout optimization problem in finite large space.
