Abstract

The simulation and measurement results of characteristics of the X-band offset reflectarray with the diameter of 460 mm on thin dielectric substrates are presented. The optimization of array main characteristics is performed using electrodynamic simulation by the full-wave method. The experimentally measured antenna characteristics are as follows: the gain is of 27.7 dB, the –3 dB main-lobe beamwidth at the frequency of 9.6 GHz is equal to 4 and 4.5° in the E- and H-planes, respectively. The operating frequency band at the –1 dB gain level is equal to 8.9–10 GHz.
