A Compact Design of High-Gain Phased Array Antenna for THz and 6G Communication Networks

Abstract

This paper explores the characteristics of an innovative linear phased array designed to provide high gain and steerable radiation patterns, tailored to meet the demands of upcoming 6G networks. The array features a schematic with eight modified dipole elements arranged in a 1×8 linear format. To improve the radiation efficiency of the dipole resonators, rectangular directors are strategically placed adjacent to each resonator. These compact resonators utilize microstrip-line feeds, optimizing their design. The proposed phased array achieves an impedance bandwidth of 1.85 to 2.15 THz at −10 dB, delivering radiation gains exceeding 12 dBi across various angles. This performance meets the requirements for 6G communications.
