Analysis of Single Square Ring Reflectarray Element for Bandwidth Enhancement
نویسندگان
چکیده
An analysis of phase variation and phase range of single square ring element for broadband reflectarray antenna is presented in this paper. The analysis and design of reflectarray antenna element is presented based on variable size of the square ring element parameter a t X-band and Ka-band. The design procedure and critical parameters are also discussed. Modifying the current distribution of square ring element, leads to a less steep phase variation and also enhancement on the bandwidth performance (up to 40.8%). The practical phase range is achieved through the use of RF35 (thickness : 1.524 mm) as the substrate. ~

Novel Element For Bnadwidth Improvement Of The Reflectarray Antenna
In this paper novel reflectarray antenna elements are proposed using aperture-coupled dielectric resonator antenna structures. Using these new structures, wide phase range and wide frequency bandwidth (up to 28.5%) with parallel and linear phase curves are obtained. In each case, an array consisting of 289 elements was simulated using the finite integration technique (FIT). The arrays exhibit 3...
