Theoretical Model of the One-Dimensional Electronic Scanning VICTS Array Antenna Radiation Pattern

This paper presents a theoretical model for a novel one-dimensional electronic scanning variable inclination continuous transverse stub (VICTS) antenna. The model integrates an electronic phase shifter between the upper radiating disk and the lower feed network disk, enabling rapid electronic scanning in the elevation plane while preserving the high gain and large-angle scanning features of the VICTS antenna. The paper develops the theoretical model for the one-dimensional electronic scanning VICTS antenna and verifies its accuracy and effectiveness through full-wave electromagnetic simulations. The simulation results demonstrate that the beam direction calculated by the theoretical model aligns closely with the full-wave simulation, confirming the model's reliability. This research lays the groundwork for VICTS antennas, with potential for low Earth orbit satellite communications requiring fast tracking and high-performance scanning.
