K-band slot reflectarray antennas

The paper studies metal-only slot reflectarray antennas characteristics. All arrays under study are designed to be manufactured with laser-cutting technique. Bandwidth dependence on geometry parameters is considered for the case of single-layer linear-polarization antenna. The analysis is based on both full-wave simulation and a solution of an integral-equation system with the Method of Moments in the spectral domain. Experimental characteristics of slot reflectarray antennas for long rectangular and dumbbell-cross elements are presented.
