Design and Analysis of Planar Frequency Doubling Reflectenna for IoT Sensor Networks

Compact and energy-efficient communication technologies are critical for the development of smart sensor networks in the constantly expanding Internet of Things (IoT) environment. This paper describes the design, analysis, and implementation of a compact planar frequency doubling reflectenna, specifically usefull for IoT sensor networks. The proposed reflectenna utilizes the frequency doubling phenomenon to enhance signal reception and transmission in IoT applications. By leveraging advanced antenna and metamaterial design principles, the reflectenna achieves efficient power conversion, reduced energy consumption, and enhanced wireless communication range. The performance of the reflectenna is analyzed through simulation and practical implementation, showcasing its potential as a fundamental component in the next generation of IoT networks. The gain of F1 antenna is 3.5 dBi and gain of mF1 antenna is 5.1dBi. Output power for frequency doubling reflectenna system observed -20dB, -89dB for distance between Tx and Rx at 100 cm, 1000cm respectively.
