Abstract

This paper investigates the design of a broadband perforated transmitarray for satellite applications in X- and Ku-bands. The transmitarray unit-cell element consists of a dielectric block with four identical holes in the center of each quadrant. These holes are used to control the transmission phase distribution on the array arrangement. An additional circular hole is drilled in the center of each unit-cell element to control the operating frequency of the transmitarray. Two transmitarrays each of 17 × 17 unit-cell elements are designed to operate at a single frequency of 12 GHz or 17.5 GHz. The peak gains of transmitarrays are 25.31 dBi and 27.1 dBi, respectively. Hybrid arrangement consisits of an alternating replacement of the unit-cell elements from the single frequency transmitarrays designed at 12 GHz and 17.5 GHz is designed and investigated. 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 from 12 to 19 GHz. The array structures are fully simulated using the finite integral technique.
