The doctoral thesis of the student Duaa Hakim Abdel Zahra, University of Basra, College of Engineering, Department of Electrical Engineering, entitled Design and implementation of printed antennas for use in Internet of Things applications, was discussed.
This study focuses on the design, implementation and fabrication of small antennas for IoT applications. These antennas are intended to provide omnidirectional radiation characteristics with reasonable gain and large communications range. Single-band antennas are designed in frequency bands commonly used for IoT applications namely the 2.4 GHz Industrial, Scientific and Medical (ISM) band and the 915 MHz Ultra High Frequency (UHF) band. In addition, two additional multi-band antenna designs were implemented. The resulting designs have sufficient gain and almost perfect matching at different resonant frequencies. The designs were compared to some previous important IoT antennas.
Comparison results show that the proposed antennas provide an excellent balance between size reduction and antenna gain values ​​within the operational range.
