Abstract

The antenna beam-steering technique based on near-field phase transformation yields antenna systems that have superior characteristics compared to the traditional methods including both mechanical and electronic. Some of the unique attributes associated with this technology are its totally passive nature, low height profile, and extremely simple operating mechanism. The technology has been used to develop two generations of antenna systems. The first generation was developed using multilayered printed metasurfaces (PMs) and the second generation used graded-dielectric plates (GDPs). In terms of radiation performance, the two antenna systems are nearly identical. The height profile of a GDP based antenna is about one free-space wavelength more than the height of a PM based antenna. PMs can only be manufactured in specialised facilities while with rapid advancements in materials and 3D printing, it may be possible to cheaply develop GDPs.
