Low-Profile/Dual-Band Planar Phased Array Patch Antenna for THz Communications

Abstract

This research presents a new 4x4 planar phased array antenna designed specifically to meet the evolving requirements of future 6G communications in the Terahertz (THz) frequency range. Each antenna element is uniquely configured, utilizing a low-profile coaxial-fed patch antenna that incorporates a rotated π-shaped slot. This innovative design enables dual-band functionality, allowing the antenna to operate effectively at both 1.5 THz and 3 THz frequencies. Furthermore, the array's fundamental characteristics demonstrate excellent radiation patterns, gain, and beam-steering capabilities, which are essential for supporting the demanding specifications of 6G technology.
