Development and construction of new scanning antennas with high remote sensing capability for wireless communication systems in the millimeter wavelength range

Abstract

In this paper, geometric methods and wave optics were used to calculate the basic profiles and characteristics of the lens antennas.  The planar reflector arrays were assembled using an iterative method with multiple forward and inverse Fourier transform calculations.  Three-dimensional electromagnetic modeling was performed in CST Microwave Studio software to evaluate the technical parameters of the designed antennas. Measurements of the characteristics of fabricated prototypes of far-field scanning antennas were performed using a custom-designed experimental setup. This study focuses on the analysis and development of scanning antennas for use in millimeter-wave wireless communication systems. The researchers aim to develop a lenticular antenna in the 57.24-65.88 GHz band with a high DER and a wide-angle radial scanning function in the azimuth plane and another lenticular antenna system in the 58-62 GHz band with a high DER and a wide scanning sector in the azimuth plane. The researchers also aim to develop a methodology to design flat reflective gratings to provide electron beam scanning in the azimuthal plane. The characteristics of prototypes of these antennas have been studied, and experimental tests have been conducted. The study predicts the realization of scanning antennas in the 57.24-63.72 GHz band using microstrip flat reflector grids.
