Concurrent Gain and Bandwidth Improvement of a Patch Antenna with a Hybrid Particle Swarm Optimization Algorithm

This paper demonstrates that antenna design and performance can be prominently improved by linking commerically available software with the Hybrid Particle Swarm (HPSO) optimization algorithm. To demostrate this technique, multiple parasitic elements were added to a conventional patch antenna and optimized for bandwidth and realized gain. HPSO is implimented with Python and a commercially available full-wave software, ANSYS High Frequency Structure Simulator (HFSS). The simulated and measured results show that antenna performance is substantiably improved in both bandwith and realized gain, with an increase of 10% in -10 dB bandwidth and approximately 15% in realized gain.
