    Abstract: A low profile solar cell integrated with reflectarray element composed of multilayer materials is presented in this study. A unit cell consist of triangular loop shape element is varied in size to get the required phase range. Some modification is then introduced to the triangular loop element aimed to optimize the bandwidth. A wide bandwidth range over 15% has been achieved. A prototype of the solar reflectarray cell was fabricated and measured. The measured results show good agreement with simulation. The element is designed to be operated at K<sub>u</sub>-band frequency and formed a solar reflectarray antenna used for terrestrial applications.
