Introduction
Determining the optimal location for an antenna on a platform is limited by the humans involved. Best guesses are based on previous experience and rules of thumb. As platforms become more complicated, determining the placement for antennas becomes an increasing challenge. This paper looks at XFdtd's, a Finite-Difference Time-Domain solver, implementation of a Genetic Algorithm (GA) for its effectiveness in determining the optimal placement of an antenna on a platform.
Background
XFdtd uses the Finite-Difference Time-Domain (FDTD) method [1] to solve general electromagnetic problems. Built into XFdtd is the concept of Feature Based Modeling (FBM), which allows relative coordinate system definitions among parts in a model. The GA [2], written in C++, is available through XFdtd's Scripting API. Through scripting, a user defines the antenna and the acceptable regions on a platform where the antenna can be located.
