In this paper. we propose an improved adaptive frequency sweep strategy based on the asymptotic waveform evaluation (AWE) technique for simulating broadband antennas across a wide frequency range. Our approach maintains high accuracy compared to traditional frequency sweep methods. as demonstrated through simulation results of several commonly used broadband antennas. https://www.bekindtopets.com/mega-save-Self-Banarasi-Brocade-p7321-limited-save/
