Design and Optimization Dipole Antenna for Next-Generation 5G/6G Networks Using HFSS.15

In this paper, we propose a dipole antenna for fifth-generation (5G/6G) wireless cellular networks. To realize a wide frequency range of operation, to examine the enactment of the simulated and modelled dipole antenna 5G then move in to dipole antenna 6G systems. This paper presents the design and simulation of a high-frequency dipole antenna suitable for 5G/6G communication systems using Ansys HFSS. The antenna operates at a center frequency of 140 GHz, placing it in the terahertz spectrum, which is essential for 6G technologies. The antenna is modeled using Ansys HFSS with a conductor radius (dr) of 0.1 mm, total length (dl) of 4.75 mm, and a 0.1 mm feed gap (gl). Despite the antenna length being significantly longer than the conventional half-wavelength at 140 GHz (λ = 1 mm), the simulated return loss (S11) confirms excellent resonance performance, indicating higher order mode operation. The design demonstrates effective impedance matching and stable resonance at terahertz frequencies, providing valuable insights into alternative high-frequency antenna configurations for THz-band communication systems. Simulation results demonstrate that the proposed dipole structure achieves good impedance matching and radiation performance at the target frequency.
