Abstract:
Coupled-resonator array antennas exploit the strong phase dispersion of coupled resonator networks to achieve beam steering with extremely high scanning rates within a narrow operational bandwidth. Unlike conventional leaky-wave antennas relying on traveling-wave phase accumulation, these arrays employ controlled coupling topologies to produce sharp phase variations across a compact aperture, enabling continuous broadside scanning with high radiation efficiency and planar compatibility. This inherent frequency-dependent beam diversity makes them naturally suited for frequency-diverse imaging and sensing, where spatial information is encoded in the spectral domain without mechanical scanning or phased-array hardware. The high scanning rate allows sufficient spatial diversity to be generated within a minimal frequency band, reducing spectrum occupation and front-end bandwidth requirements. This talk provides an overview of the operating principles, design methodologies, and emerging applications of coupled-resonator array antennas in the context of frequency-diverse sensing. Biography:
