Magneto-Dielectric Antenna Designs using Material and Metallic Genetic Algorithm Optimization

This paper presents several antenna designs based on magneto-dielectric and metallic antenna optimization. This is done using genetic algorithms (GA) and various designs are considered for a set of dielectric, magnetic and metallic choices. The optimized final designs include very thin, single layer textured dielectric (~0.01 lambda) substrates for circular polarized (CP) conformal antennas with as much as 15% bandwidth (BW) and sizes of the order of 0.1 lambda to 0.3 lambda (always thin ~0.01 lambda) exhibit remarkable gain or bandwidth behavior. Multiple designs are presented demonstrating the easiness and originality of the present approach
