  • Abstract In last decades, there are more and more structures that can be simulated by the computer, including from the basic microstrip antennas, to the large metal structures, like ships or airplanes. In the early stage, it is a hard mission to calculate the structures with big size like this because of the price and volume of computer memory are both huge. Nowadays, people can easily get enough memory for the simulations of large structure, and this is a great help for the engineers of big structures design.
    Those large metal structures with complex wireless communication systems, like ships and airplanes, need to think about whether the antennas can work normally or not while designing. The narrow space is not only makes the patterns incomplete by metal shelters, but also may cause the interference of the antennas.
     It always costs a lot of time and money on this kind of large structures, no matter when designing or building. If we measure the performance of the antennas after it is done, the problems of the structures will be hard to correct.
    The target of this paper is using computer to simulate the performance of the antennas installed at the different position. Then we use the scaled down model to measure the patterns in the chamber, and compare the difference between measurement and simulation.
