Optimization for Frequency-Diverse Meta-Waveguide Antenna
Published in 2026 IEEE 14th Asia-Pacific Conference on Antennas and Propagation (APCAP), 2026
To address the challenge of maintaining wideband impedance matching for frequency-diverse meta-waveguide antennas (FDMWAs) in computational microwave imaging (CMI) systems, this paper proposes an optimization method based on a reflected-wave phase-cancellation mechanism. By preserving the low correlation among the radiation patterns, the approach significantly enhances the impedance matching bandwidth. Full-wave simulation results demonstrate that the optimized FDMWA achieves an S11 below -10 dB across 32-36 GHz and generates 40 low-correlation pseudo-random radiation patterns, leading to improved overall antenna performance.
