Metamaterial-Based Mm-Wave Phased Array for Broadband Cellular Networks

Abstract

A new broadband phased array antenna with wide-scan and high-gain beam-scanning are desirable to meet the requirements of future cellular networks. This paper discusses the characteristics of a new beam-steerable array design having broad bandwidth for 5G communications. The discussion is focused on smartphones, due to their small size and complexity. The design procedure is straightforward and accomplished on a mainboard of future smart handheld devices. The introduced phased array design involves eight metamaterial-based dipole resonators with a 1×8 linear form. The resonators have small sizes with microstripline feedings. For -10 dB, the design represents 28-38 GHz covering several bands in the 5G spectra. © 2023 IEEE.
