Abstract

Continuous Beam-Steering Low-Loss Millimeter-Wave Antenna Based on a Piezo-Electrically Actuated Metasurface

Highlights

  • M ILLIMETRE-WAVE frequencies offer a promising solution for emerging broadband mobile communications such as 5G and beyond

  • Antenna beam steering of around 45° may be desirable for non-line of sight (NLOS) communication, depending on the number of sectors in a cell of the 5G base station, and up to 10° for a line of sight (LOS) link [1], [2]

  • In order to test the configurability of the high impedance surface (HIS) in isolation from the rest of the Leaky-Wave Antenna (LWA), and to demonstrate the feasibility of a piezoelectric actuator tuned device, the HIS was patterned onto a RT/Duroid5880 substrate with 35 μm rolled copper cladding

Summary

INTRODUCTION

M ILLIMETRE-WAVE (mm-wave) frequencies offer a promising solution for emerging broadband mobile communications such as 5G and beyond. A tunable, piezoelectric actuator (PEA) based, high impedance surface (HIS) was recently developed as an electro-mechanically tuned phase shifter exhibiting relatively low loss performance in the mm-wave band [24],[25]. A low loss (
