초록
The scattering solutions for a metallic-rectangular-grooves based two-dimensional (2D) reflectarray antenna excited by an open-ended parallel-plate waveguide are obtained using an overlapping T-block method and the Stratton-Chu formula. The design formulas of a reflectarray antenna to obtain high directivity and beam-tilting effect are also proposed in view of the phase matching condition. The scattering characteristics of a metallic-rectangular-grooves based 2D reflectarray antenna are computed in terms of 2D antenna gain and focus offset. We manufactured the metallic-rectangular- grooves based 2D reflectarray antenna for f = 60 [GHz] and measured the radiation pattern and three-dimensional antenna gain by means of near-field antenna measurement. © 2006 IEEE.
