Performance Metrics Comparison in IMT-E Band between Lens Antenna and Helical Antenna at 2.6 GHz – A Statistical Approach

This study focuses on a thorough examination of two antenna designs that operate in the IMT-E band at a centre frequency of 2.6 GHz: the lens antenna and the helical antenna. For analysis, a total of 28 samples are gathered and split into four groups. The information is provided under the section on proposed work. Lens antennas in Group-1 have a lens thickness of 0.07; lens antennas in Group-2 have a lens thickness of 0.05; helix antennas in Group-3 have a frequency range of 2.2 GHz to 3.2 GHz; and helical antennas in Group-4 have a frequency range of 2.4 GHz to 2.8 GHz. The FEKO software is used to design the antennas, and the SPSS tool is used to do a comparative study. The enhanced performance of the antennas is demonstrated by the statistical significance (p=0.0, p<0.05). The lens antenna in Group-1 with a 0.07 lens thickness shows a gain of -9.39 dB, and the lens antenna in Group-2 with a 0.05 lens thickness shows a gain of -8.79 dB. With a frequency range of 2.2 GHz to 3.2 GHz, the helical antenna in Group 3 obtains a gain of -7.482 dB. Similarly, the helical antenna in Group-4, operating in the 2.4 GHz to 2.8 GHz frequency range, achieves a gain of -7.467 dB. The creative antenna design in Group-4, which uses a helical antenna with a frequency range of 2.4 GHz to 2.8 GHz, is found to perform noticeably better than the other groups through one-way ANOVA testing. In the IMT-E band at 2.6 GHz, this comparison study offers insightful information about the performance parameters of helical and lens antennas. The findings demonstrate the potential of Group-4’s creative antenna design, providing opportunities for more study and advancement in the area of wireless communication systems.
