Analysis of Efficiency in Dual-Band Antenna for 5G Using FR4 Substrate and Compare with RT Duroid Substrate

Abstract

This study involves developing a compact dual-band antenna for FR4 and comparing its efficiency to a dual-band antenna for RT duroid. Materials and Methods: The antenna was made using an efficiency that was built on a commercially available FR4 substrate with a thickness of 2.6 mm. The performance was analyzed with the aid of Ansoft HFSS version 13.0 software. The sample size is estimated to be 32 using the G Power statistical tool with a probability of 80%. Results: In this study, a return loss of -33.15dB and -21.06 dB at 12.7GHz followed by 15.4GHz, and efficiency is 0.3 is obtained. The significance of RT duroid substrate value is 0.001 which is less than (p < 0.05). Conclusion:The Efficiency is high at 2.8 GHz frequency in novel RT duroid substrate (-0.14105 dB) compared to FR4 substrate (-10.445 dB).
