description: This work presents the results of the development of a compact printed irradiator of the C-frequency range for a T-55 two-mirror toroidal antenna of satellite television. The results of the study of the possibility of combining this irradiator with a Ku-band scalar horn to use a dual-band irradiator as part of the T-55 two-mirror toroidal antenna for radiometric complexes of remote sensing of the earthâs surface from unmanned aerial vehicles are also presented.
The optimal geometric parameters and characteristics of the C- and Ku-band irradiators of the T-55 two-mirror toroidal antenna are calculated.
Computer electrodynamic modeling of the C-band strip irradiator 3.4 - 4.2 GHz was performed.
The radiation patterns for the four-element antenna array with microstrip patches are obtained.
The optimal parameters of the C-band irradiator were selected in such a way as to provide illumination of the edges of the elliptical auxiliary mirror in the angular sector of + -35 degrees at a level of ~- (9-12) dB.
