With the goal of improving Voltage Standing Wave Ratio (VSWR) characteristics, this suggested research developed a new Split-Ring (SR) substrate-integrated waveguide (SIW) antenna and compared its performance to that of SIW antennas. In terms of analysis, the estimated sample size was 32, and the pretest power was around 80%. There were two groups that were considered for the suggested design: one had a slotted SIW antenna with sixteen samples, and the other had a SR-shaped substrate-integrated waveguide antenna with sixteen samples. As far as VSWR is concerned, the novel SR-shaped SIW antenna performs better than the slotted SIW antenna from 20 to 40 GHz, with values as low as 0.49, 0.78, 0.82, 0.93, 0.96, and 0.82 GHz. The VSWR values for the two groups of participants vary significantly, with a significance level of 0.042 (P < 0.05). To measure how well this antenna worked, we utilized the Ansys HFSS Electronics Desktop 2021 R1 (HFSS 2021 R1) program. The SR SIW antenna has a lower VSWR at 25 GHz, 0.78 at 28 GHz, 0.82 at 30 GHz, 0.93 at 32 GHz, 0.96 at 34 GHz, and 0.82 at 38 GHz, in contrast to the slotted SIW antenna’s VSWR of 0.87 at 38 GHz.

摘要

With the goal of improving Voltage Standing Wave Ratio (VSWR) characteristics, this suggested research developed a new Split-Ring (SR) substrate-integrated waveguide (SIW) antenna and compared its performance to that of SIW antennas. In terms of analysis, the estimated sample size was 32, and the pretest power was around 80%. There were two groups that were considered for the suggested design: one had a slotted SIW antenna with sixteen samples, and the other had a SR-shaped substrate-integrated waveguide antenna with sixteen samples. As far as VSWR is concerned, the novel SR-shaped SIW antenna performs better than the slotted SIW antenna from 20 to 40 GHz, with values as low as 0.49, 0.78, 0.82, 0.93, 0.96, and 0.82 GHz. The VSWR values for the two groups of participants vary significantly, with a significance level of 0.042 (P < 0.05). To measure how well this antenna worked, we utilized the Ansys HFSS Electronics Desktop 2021 R1 (HFSS 2021 R1) program. The SR SIW antenna has a lower VSWR at 25 GHz, 0.78 at 28 GHz, 0.82 at 30 GHz, 0.93 at 32 GHz, 0.96 at 34 GHz, and 0.82 at 38 GHz, in contrast to the slotted SIW antenna’s VSWR of 0.87 at 38 GHz.
