This paper investigates the design of broadband perforated transmitarray for satellite applications in X- and Ku-bands. The unit-cell element consists of a dielectric block with four identical holes in the center of each quadrant and is used to control the transmission phase distribution. Another circular hole placed in the center of each unit-cell element and is used to control the operating frequency of the transmitarray. Two transmitarrays each of 17×17 unit-cell elements are designed to operate at 12 GHz and 17.5 GHz. The peak gains of transmitarrays are 25.31 dBi and 27.1 dBi, respectively. An alternating replacement of the unit-cell elements from the transmitarrays designed at 12 GHz and 17.5 GHz are employed. The hybrid arrangement is used to enhance the gain bandwidth of the transmitarray. A broadband gain response is achieved with 2.4 GHz over the band extended from 12 GHz to 19 GHz.
