Fractal microstrip antennas represent a groundbreaking evolution in RF engineering, combining geometric optimization with compact design principles. These antennas leverage recursive fractal patterns to achieve multiband operation within minimal spatial footprints – typically 40-60% smaller than conventional rectangular patches. Recent studies demonstrate 72% improvement in bandwidth scalability across 1.8-5.8 GHz ranges compared to standard microstrip designs.
