Analysis of a New Design Structure for Reflectarray Antennas

The key factor in the designing of reflectarray antennas is the determination of the phase range of each element constituting the antenna array, this parameters is improved by introducing slots in the radiating element, and by adjusted their dimensions. A novel structure of radiating antenna is developed whose geometry is Bowtie. The reflection coefficient phase is obtained by the unit cell waveguide approach under the CST Microwave Studio.
