Abstract

Slot-loading rectangular DRA elements reflectarray antenna was designed for linear polarization at X-band. The antenna was center fed by a linear polarized pyramidal horn. The array size is 23 x 23 elements reflectarray. The finite integration technique was used to compute the radiation patterns and the gain of the antenna. The method was verified by comparing the results with transmission line method and was found to be efficient and accurate for these analyses. The antenna achieved a 3-dB beamwidth of 8° with a gain of 26 dB at 10 GHz.
