Application of Coherently Radiating Periodic Structures for Feeding Subarrays in Limited-Scan Arrays
IEEE Open Journal of Antennas and Propagation, 2023 This paper presents a new design technique to improve the reduction of phase shifters using sub-arrays and CORPS (coherently radiating periodic structures) technology. The CORPS network generates the values of cophasal excitation with reduced input ports.

Verification of Phase Shifter Measurements of a Reflective Array Antenna
Известия высших учебных заведений России: Радиоэлектроника, 2021 Introduction. Large-size phased antenna arrays (PAA) frequently incorporate optical excitation schemes, whose main elements include the feed and the reflective aperture. In turn, the reflective aperture consists of several tens of thousands of radiators
