Design of X-Band Reflect Array Antenna using Circular Ring Patches
By using the size variation technique of the patch, a high gain reflect array antenna which can be easily fit in a small satellite, has been analyzed in this study. The unit cell consisting of a ring patch and a square slotted circular patch has been designed for the best performance of 9×9 reflect array antenna. This unique form of unit cell is constructed on a thin dielectric layer with a 0.183×freespace wavelength thickness and two circular ring patches. By using the size variation technique of the patches, 350° moderate phase variation is obtained by simulating in proper boundary condition. On a square 2D plane, the reflect array antenna has 81-unit cells with a center feed horn antenna. At 10GHz, the planned reflect array offers 96% antenna efficiency. The reflect array antenna’s gain margin is 20dBi at 10GHz, with a 21% 1-dB gain bandwidth and a 28% 3-dB gain bandwidth, according to the simulation results.
