Abstract
The transmission of signals through an antenna having a microstrip H0 slot patch, provides the lowest feasible return loss when compared to various substrate materials for use in the S-band in the specified frequency range. This research suggests an antenna design with FR4 substrate, Duroid 6010, RT-Duroid 6080, nylon fabric, and other materials. The proposed antenna has the following measurements: 39.2 mm x 39.2 mm x 1.6 mm. The High-Frequency Structure Simulator 19.0 is used to generate the full design and examine the reflection coefficient. With a reflection coefficient of −17.37dB, −21.81dB, - 23.42dB, and −23.68dB, Duroid 6010, Rt-Duroid, Nylon Fabric, and FR4 substrates are used to design the innovative H slot microstrip patch antenna. At the resonant frequency range of 2.4 GHz, this cutting-edge proposed antenna with FR4 substrate offers superior signal transmission. S-band applications mostly employ this frequency range. Simulation results show that the proposed antenna with FR4 substrate has a significantly lower return loss (-23.68 dB) than the conventional antenna with a different substrate material.
