Description
A method is demonstrated for generating compact, broadband and multiband antennas using ellipses to create new amorphous shapes with greater bandwidth and less return loss that previously demonstrated. Four designs are presented including a tri-band patch antenna optimized for low reflection loss at 1.6, 1.8, and 2.45 GHz. A broadband patch is designed for 1.9–2.1 GHz. A dual-band design embedded in a dielectric is created for use at GSM frequencies, and a broadband monopole is created that operates from 2–6 GHz with low reflection loss. The genetic algorithm is used to optimize the designs. FDTD is used to simulate the designs allowing a low reflection loss design embedded directly into a heterogeneous structure or dielectric material.
