Gain Enhancement of Novel Rectangular Microstrip Patch Antenna using RT-Duroid substrate and FR-4 substrate on S-band

Abstract

The aim of this work is to construct an antenna with improved gain using novel RT-Duroid substrate. The RT-Duroid rectangular patch antenna is developed to improve antenna gain by utilising FEKO software and gathering a database of 40 samples with a pretest power of 80%, an alpha error level of 0.05, and a 95% confidence interval. The Novel antenna is suited for frequencies ranging from 2 to 3 GHz. According to the findings of this investigation, the RT Duroid design looks to be superior to the FR-4 patch antenna. RT DUROID patch antenna design is having more gain (71 %) and directivity (58 %) with comparison of FR-4 patch antenna design.
