A novel phasing line is proposed to improve the reconfigurability frequency range of an aperture-coupled reflectarray unit cell. A couple of broadband radial stubs loaded by a single varactor diode is adopted to realize the dynamic phase shift mechanism, extending the unit cell beam-scanning and/or reshaping pattern capabilities within a broader frequency range. The radiating structure is properly optimized at 11.5 GHz, obtaining a full phase tuning range within a very large frequency span of about 1.35 GHz.

Abstract
A novel phasing line is proposed to improve the reconfigurability frequency range of an aperture-coupled reflectarray unit cell. A couple of broadband radial stubs loaded by a single varactor diode is adopted to realize the dynamic phase shift mechanism, extending the unit cell beam-scanning and/or reshaping pattern capabilities within a broader frequency range. The radiating structure is properly optimized at 11.5 GHz, obtaining a full phase tuning range within a very large frequency span of about 1.35 GHz.File in questo prodotto:
