Abstract: This work presents a novel wireless interrogator designed to efficiently interface with passive electromagnetic sensors, addressing critical challenges in energy efficiency and real-time IoT connectivity. The Internet of Things (IoT) is transforming a wide range of industries, enabling real-time monitoring and information collection through interconnected sensor networks. Passive electromagnetic sensors, which do not require an external power source, offer significant advantages in energy efficiency and maintenance-free operation. However, efficient data interrogation and communication from these sensors remain a challenge, particularly in IoT-based wireless applications. The design and development of a wireless IoT interrogator for passive electromagnetic sensors are described in this paper. The proposed interrogator leverages advanced wireless communication protocols and energy-efficient techniques to interrogate passive sensors, retrieve data, and transmit it to IoT networks for real-time monitoring and analysis. We analyze the system's performance through experiments, highlighting the interrogator's capability to support diverse IoT applications, such as environmental monitoring and smart agriculture. The proposed system is energy-efficient, scalable, and capable of supporting real-time data transmission to IoT networks, making it ideal for a wide range of IoT applications. F1 antenna gain is 3.50 dBi, and mF1 antenna gain is 5.10 dBi. Output power for frequency doubling reflectenna system observed -20dB, -89dB for distance between Tx and Rx at 100 cm, 1000cm, respectively.
