Abstract

To compare and analyse the innovative isotropic T-shaped antenna's enhancement of gain through the use of a Kevlar substrate with an FR4 substrate. Materials and Methods: This paper conducts a correlational analysis of two methods: the innovative isotropic T-shaped antenna utilizing a Kevlar substrate and the FR4 substrate, both employed for designing the innovative isotropic T-shaped antenna. Two groups have been considered for comparative analysis, with the calculation of the sample size facilitated by the G-power application. One group pertains to the Kevlar substrate, and the other group involves the FR4 substrate. Each group consists of 10 samples, resulting in a total sample size of 20. The alpha error threshold is set at 0.05, accompanied by a 95% confidence interval and 80% power. The outcomes have been derived using HFSS software. The gain achieved by the innovative isotropic T-shaped antenna utilizing a Kevlar substrate, intended for aerospace applications, is 9.4 dB. This performance is significantly better than that of the T-shaped antenna employing the FR4 substrate, which attains a gain of 2.8 dB at a frequency of 2.4 GHz. Notably, a significant gain disparity exists between the two substrates, with a two-tailed significance value of 0.001 (p<0.05) as established by independent samples t-tests. The innovative isotropic T-shaped antenna, utilizing a Kevlar substrate, achieves a gain of 9.4 dB at 2.4 GHz, featuring an index of 2.2 and a thickness of 1.6 mm. This performance surpasses that of the T-shaped antenna using the FR4 substrate.
