A triple-slot patch antenna integrated with Electromagnetic Band Gap (Mushroom Electromagnetic Band Gap, Electrical Electromagnetic Band Gap) structures is designed to enhance wireless communication performance for IoT applications. It combines a compact triple-slot patch design with periodic EBG unit cells that suppress surface waves and improve gain and directivity. The antenna design is simulated at 5.5 GHz using ANSYS Electronic Desktop to evaluate its overall performance. ANSYS Electronic Desktop is used to model and simulate the proposed antenna at a resonance frequency of 5.5 GHz, allowing for an accurate assessment of its electromagnetic behavior. Key factors such gain, voltage standing wave ratio (VSWR), return loss (S11), bandwidth, and far-field radiation patterns are examined to complete a thorough performance study. Lower return loss values and a VSWR that is closer to unity throughout the operating frequency band are the results of the integration of EBG structures, which also significantly improves radiation characteristics and impedance matching. Furthermore, a more stable radiation pattern with higher directivity and lower back-lobe radiation is shown by the far-field data. The analysis focuses on key parameters such as gain, voltage standing wave ratio (VSWR), return loss, and far-field radiation characteristics. The results indicate a significant improvement compared to conventional antenna designs. The antenna’s compact size, improved gain, and minimized surface wave effects make it suitable for powering IoT enabled devices in home automation, industrial wireless monitoring, and other low-power communication systems.
