A Novel Structured Antenna with Microstrip Line Fed for Low-Band 5G Applications

With a focus on sub-6 GHz band, this paper introduces a unique axe-shaped antenna design for 5G communication applications.A 1.6 mm-thick antenna patch is carefully etched over a FR4 substrate with a dielectric constant of = 4.3 and fed via a line feed method.By using a defected ground construction method, the radiator's mirror image is finely etched onto the ground plane.The total size of the suggested design, which was modeled with CST Microwave Studio, is 48.5 24.5 1.6 mm.Several performance factors have been closely monitored in this study, including Surface current distributions, S-Parameter, Antenna Gain and Radiation patterns.The antenna shows great benefits for 5G communication applications with a stable gain of 4.6 dB at the resonating frequency of 3.5 GHz and a simulated and measured bandwidth of 470 MHz (13.4 % fractional bandwidth) and 489 MHz (14.1% fractional bandwidth), respectively.The resonating band is within the mid-band frequency range assigned for 5-Generation networks.A prototype of suggested antenna was characterized using a Vector Network Analyzer (VNA-N5247A) to confirm its effectiveness for 5G, and the findings showed a strong degree of agreement with the simulations.
