Abstract

The design and fabrication process of a dual-band 1.2 m reflectarray was presented in this paper. This reflectarray was designed for two frequency bands: 11.4 GHz 12.8 GHz for the receive and 13.7 GHz 14.5 GHz for the transmit. An optimization technique was introduced to minimize the adverse effect of frequency dispersion on the level of gain at the receive band. Different classes of double cross open loop elements were utilized in the design of the elements for the receive band and double square open loops were used for the transmit band. The bandwidth of reflectarray at receive band was improved significantly by using the optimization method.
