Broadband Antenna for Use Over Varying Ground Conditions
Devices designed for free space operation often fail to meet expectations when deployed in their actual environment. This study considers the example of designing a broadband antenna for an unattended ground sensor using Remcom's XFdtd. To address the challenge of attaining acceptable performance over both dry and wet ground conditions, we use Particle Swarm Optimization (PSO). XStream GPU Acceleration and MPI + GPU technology make this type of sophisticated simulation strategy possible, completing multiple optimizations with hundreds of generations to converge on the best values.
