In this paper, the authors describe a method for finding an optimal placement for a system of antennas. Determining the location of multiple antennas for a single fixed or mobile platform is a challenging task because of the various factors such as mutual coupling, multipath, obstructions and parasitic effects due to the platform. Placing the antennas on a huge platform requires a long, manual effort. An automated program will not only save the time but also gives the optimal placement. In this paper, they have used a genetic approach to find the best placement for a set of antennas.
