A Low-Profile Circular Array Antenna Design for Terahertz MIMO Communications

Abstract

This study introduces a new MIMO antenna design featuring low-profile and closely spaced loop antennas strategically placed at the various sides of a low-profile circular Rogers 5880 board with a radiator of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$100 \mu \mathrm{m}$</tex>. The antenna elements operate efficiently within the frequency range of 2.1-2.3 THz, offering polarization diversity and full radiation coverage for comprehensive connectivity. Through extensive simulations, the performance and potential of the MIMO antenna system are thoroughly evaluated, yielding promising results for future 6 G.
