Abstract

Single-layer circularly polarized (CP) reflectarrays in the Ka-band are presented in this paper. Three reflectarray (RA) models are designed and measured, using geometrically dissimilar elements. Each element is analyzed individually and optimized to obtain good performance within the operating frequency band. To compensate the spatial delay from feed to the elements at RA surface, the angular rotation technique has been employed for obtaining reflected phase curve. The performances of the antennas are analyzed at 30 GHz, exhibiting 13.3% of 1.5 dB gain bandwidth, while the axial ratio bandwidth is less than 3 dB in the whole operating band.
