摘要: Reflectarray antennas realized by rectangular and crossed dielectric resonator for linear circular polarization, respectively, in X-band are investigated. The reflectarray is center fed linearly polarized pyramidal horn antenna. Full-wave analysis using the finite integration technique applied. mutual coupling between feeding elements of considered. A 15.5% bandwidth achieved with 1 dB gain variation case designed at 10 GHz. has a 25 dBi. cross-polarization very low about −55dB below main beam peak. 3-dB beamwidth 5°. Circularly antenna feed presented. 169-element designed. For frequency band 8.2 GHz 10.3 GHz, from 15.6 dBi to 18.5 dBi, axial ratio 3 dB.
