Circular Antenna Array with Full Radiation Coverage for THz Communications

This paper investigates the features of a new THz array that exhibits high-gain and steerable radiation capabilities, catering to the needs of 6G networks. Its schematic incorporates eight dipole elements arranged in a circular configuration. To enhance the radiation properties of the resonators, directors are positioned alongside each dipole resonator. The dipole resonators are compact in size and employ microstrip-line feeds. The antenna elements operate efficiently within the frequency range of 1.85- 2.15 THz, offering polarization diversity and full radiation coverage for comprehensive connectivity. Through extensive simulations, the performance and potential of the antenna are thoroughly evaluated, yielding promising results for future 6G.
