Abstract

In this work, a detailed analysis of dual frequency X-band reflectarray antenna using dual gap configuration on the rectangular patch element is presented. A novel method of moment mathematical model of dual frequency operation based on different dielectric material has been introduced in this paper. The analytical modeled simulations and mathematical model of dual frequency using Roger RT/d 5880 and FR-4 as dielectric substrate operation offers a good agreement. The numerical analysis results based on Finite Integral Method (FIM) computer model of CST MWS show that employing dual gap on the rectangular patch element improves the static phase range up to 343.5º. The design and measurement setup of proposed configurations are discussed in this paper. The comparisons between simulations, mathematical model and measured results have also been presented.
