The rapid proliferation of Internet of Things(IoT) devices increases the demand for a strong communication system. Since microstrip patch antennas are compact in size, low profile, and easily integratable, they become a preferred choice. However, conventional designs generally work on a single frequency, restricting their applicability in IoT applications where multi-band operations are necessary. In this paper, a dual-band microstrip patch antenna is proposed for IoT and Wi-Fi applications. This antenna operates on a frequency of 900 MHz for IoT and a frequency of 2.4 GHz for Wi-Fi applications, which facilitates device communication on both bands simultaneously for enhanced performance and functions. The antenna is designed using an FR4 substrate of 1.5 mm in thickness, having a dielectric constant of 4.4. These simulation and analysis results further validate the antenna performance metrics in terms of resonant frequency, bandwidth, and radiation pattern. The results obtained clearly confirm the efficiency of the antenna for IoT and Wi-Fi applications.
