Abstract

The demand for low cost and less weight antenna with compact broadband features in communication system is rapidly increasing. In this work, the possibility of employing dual gap on reflectarray patch element for static phase rangeperformancewith enhanced dual frequency operation of reflectarray antenna are presented. By introducing dual gap on rectangular patch element, the static phase range is shown to be significantly increased for dual frequency operation from 294.40° to 343.50°. Moreover, 49.1° enhancement in static phase range offers a reduction in the phase error produced by the limited static phase range of 4.58% demonstrated. Additionally, a novel formulation of dual frequency reflectarray antenna based on Finite Integral Method (FIM) has also been developed. The comparison between simulated and measured results is also presented in this work. Several parameters of reflectarray antenna such as bandwidth performance and static phase range are discussed in this paper.
