A Study on Modeling of Geometrical and Physical Parameters of Waveguide Transmitarrays

Abstract

The demand for high gain antenna operating at millimeter wave (mm-wave) frequencies has been increasing exponentially. Applications like satellite communications, fifth-generation (5G) mobile communications, remote sensing etc., need long distance communication, wider coverage, narrower beam width from an antenna. Transmitarray antenna could be a potential solution to meet these demands. A transmitarray antenna combines the advantages of phased array antenna and lens antenna. For operational simplicity, waveguides operating in fundamental modes are chosen as the array elements. The geometrical and physical parameters of the transmitarray greatly influence the radiation performance of the antenna. Hence in this paper a detailed study of these parameters is done for both single and multiple beam antennae.
