Abstract
The results of design and experimental investigation of a multibeam planar three-layer double-reflector system in the millimeter wave band are presented. A Schwarzschild aplanatic reflector system with symmetric generatrices is considered. The system parameters have been chosen as a result of optimization of this system with the use of the method of physical optics and the Pareto criterion. A prototype of an integral quasi-optical system in the form of a multilayer printed circuit board containing an aplanatic double-reflector optical system illuminated by an array of 19 microstrip horns has been manufactured. Experimental studies have been performed at a frequency of 36 GHz; a set of beams with fan-shaped radiation patterns in a coverage sector of ±38° has been obtained. The experimental data are compared to the results of calculation.
