Measurement and optimization of a continuously tunable 10×10 reflectarray antenna for 5G metrology in the K-band

Abstract

A functional 10×10 reflectarray antenna is developed for millimeter-waves. It has a gain of approximately 10 dBi and a continuous steering range from −30 to 30∘ in the horizontal plane. In this paper, the entire design process is explained, beginning with the design and function of the antenna element and followed by considerations regarding positioning of the feed antenna. Steering and controlling of the beam are discussed. Finally, the antenna patterns for different steering angles were measured in an anechoic chamber. The design is scalable, built with commercial off-the-shelf components, and the array does not need active cooling.
