Recent investigation of wideband millimeter-wave dielectric reflectarray in Beijing Institute of Technology
Several wideband millimeter-wave dielectric reflectarray antennas are discussed in this paper. Different phase distributions are realized by changing the shape or material of the array element. Three dielectric reflectarray of 20×20 elements operating at 100GHz are compared. The 1dB gain bandwidths of the dielectric reflectarray are larger than 10% and up to 40%. As compared to the microstrip reflectarray, the dielectric reflectarray can reduce the metal losses and effectively improve the gain bandwidth.
