Abstract

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 at 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.
