This study presents the design, modeling, and analysis of a hexagonal ring slotted microstrip antenna suited for 470 MHz center frequency Applications for the Industrial, Scientific, and Medical (ISM) band. The antenna's operating frequency of 470 MHz is specifically intended for it. The FR-4 substrate has a relative permittivity of 4.4 and a thickness of 1.6 mm, is used in its construction. The antenna's physical dimensions are 124 × 124 × 1.6 mm³, and it functions at the previously indicated frequency in the ISM range. Software for electromagnetic modelling is used to analyse and design the antenna in order to evaluate various performance measures, such as the S11 parameter, radiation pattern, and voltage standing wave ratio (VSWR). The results indicate that the proposed hexagonal ring slotted microstrip antenna is suitable for 470 MHz ISM band applications due to its good performance characteristics, including reduced VSWR, preferred radiation patterns, and acceptable S11 parameter values.
