Design, Analysis and Measurements of Reflectarray using Variable Length Microstrip Patch Antennas at Ka-Band

For design of reflectarray antennas, microstrip patches of varying length provide an attractive alternative. In this paper the analysis, design and measurement of reflectarray antenna based on variable size at Ka-band is presented. The design procedure and critical parameters are discussed. For our analysis we employ a full wave solution, i.e., method of moment (MoM). This solution is made efficient using threads and parallel processing techniques. To validate our analysis, number of arrays are built and measured, showing a good agreement with the simulation results.
