Automobile conformal antenna design and optimization using genetic algorithm

The use of conformal antennas for vehicle applications is growing rapidly due to new considerations such as styling and security. In automobile antenna design, there exist geometrical constraints and several requirements for antenna specifications, for example, directional gain patterns and polarization. In this paper, new FM frequency band conformal antennas for the automobile applications are designed using a genetic algorithm (GA). Azimuthal gain patterns and input impedance of the new designed conformal antennas are presented.
