Abstract: Wireless communication systems today demand high reliability and adaptability as signal quality constantly varies due to interference, environmental obstacles, and user mobility. However, conventional fixed-frequency antennas lack the ability to adjust to such dynamic conditions, resulting in signal degradation, reduced coverage, and unstable communication. To address this limitation, this project proposes an AI-Powered Adaptive Frequency Antenna System capable of intelligently switching between multiple microstrip patch antennas tuned to 2.4 GHz, 3.7 GHz, and 5.5 GHz. A Software Defined Radio (SDR) module is used to capture real-time signal data, while a Raspberry Pi processes key parameters such as Received Signal Strength Indicator (RSSI) and Signal-to-Noise Ratio (SNR) using AI-based decision-making algorithms. Based on the analysis, the system automatically selects and activates the antenna that provides the best communication performance through a relay or RF switch. This adaptive approach ensures stable connectivity, improved signal quality, optimized bandwidth usage, and energy-efficient operation. The proposed system offers a low-cost, scalable, and intelligent solution suitable for applications such as IoT networks, smart infrastructure, mobile communication, and next-generation wireless systems.
