Abstract:
The paper presents the results of studying the influence of matching layers on reflection coefficient $S_{11}$ of a scanning antenna based on multilayer dielectric structures. In view of minimizing return losses, the use of different matching layers in the scanning antenna is considered. It is shown that the two-layer structure provides a wider matching bandwidth than the single-layer one (by 7.4% at the $S_{11}$ level no more than -13 dB). The $S_{11}$ level is not higher than -13 dB in the frequency band of 10.7–12.7 GHz for the deflecting structure with two matching layers and not higher than -17 dB for the scanning antenna.
