摘要: A center-fed single-layer, dual-band reflectarray antenna is presented in this letter. Each element consists of a square ring and patch, with slots on it. The proposed operates two bands (X Ku), it uses only one horn as feed, fixed position. By varying the size elements, required phase shifts X- Ku-bands are obtained. Measurements show maximum gain 23.4 dB at 8.2 GHz 33%, 3-dB bandwidth 17%, 1-dB 25.7 dB 13.2 GHz 30%, 14%, bandwidth.
