In this study, a rectangular microstrip feed antenna on a fire-retarded substrate is presented. e antenna is designed using Computer Simulation Tool (CST) software. Different materials are used for the substrate, and the electromagnetic properties of the proposed structure are analyzed for each material. e EM property variation for each material is comparatively presented. e proposed antenna has CSRR (Complementary Split-Ring Resonator) which is engraved on the radiating element, and the shape of the CSRR is the hexagon. e proposed metamaterial-inspired antenna exhibits multiband operation at 2.1 GHz, 2.6 GHz, 4.6 GHz, 5.5 GHz, 6.1 GHz, and 7.1 GHz. With the help of material analysis, the fire-retarded substrate is chosen for the design, its excellent EM properties, and cheap cost. e photolithography-based printed antenna is validated with the help of S 11, VSWR, gain, directivity, surface current distribution, and radiation pattern. Simple, compact structure, good gain, stable radiation pattern, and excellent EM properties of the fire-retarded substrates make it suitable for the GHz application. 1. Introduction e property of the materials used in the construction of any microwave device will directly affect the performance of the microwave device, the prerequisite for any microwave device design is the material selection knowledge. ere are plenty of microwave materials available to manufacture micro- waved devices, such as CNT, magnetic and ferrite materials, flexible materials, and metamaterials [1]. e selection of materials based on the range of operating frequency is another major requirement. ere are a variety of micro- wave devices [2–4] such as antennas [5], filters, couplers, isolators, and mixers. Out of which, the antenna plays a vital role in all wireless applications. e antenna is a device made up of conductors that can convert the vibrating electrons into the EM signal during transmission and vice versa during the reception [6, 7]. Two decades before the antenna is of larger size; there are plenty of antennae-like dipoles, reflectors, slots, horns, etc. During the past two decades, there has been an enormous development in antenna design due to the development of wireless communication [8, 9]. e primary requirement of an antenna is compact size and multifunctionality. Both these essential requirements will depend on the antenna substrate. e amount of space Hindawi Advances in Materials Science and Engineering Volume 2022, Article ID 7489680, 12 pages https://doi.org/10.1155/2022/7489680
