Abstract:

Internet of Things (IoT) or machine-to-machine (MTM) communication is the most dominating communication paradigm. With the continuous development of sensors and other supporting hardware, the current development of human-Machine interactive devices to experience MTM and virtual reality has made rapid progress. To support such technological challenges and opportunities, easy to use and easy to carry interactive communication and control interfacing tools are required. A dielectric resonator (DR) spectacle antenna (DRSA) to support smart eyewear for IoT and virtual reality application is proposed in this manuscript. Both the temples or arms of the spectacle are designed to work at different frequency band, respectively. The left temple antenna (LTA) is designed to support Wi-Fi (2.4 and 5.00 GHz) and Wi-MAX (3.6 GHz) band application whereas, the right temple antenna (RTA) supports Bluetooth (2.4–2.48 GHz) band applications. For both the antennas, planar structure is designed over FR4 substrate and for DR polylactic is used. Microstrip line feeding technique of excitation is used for both the antennas. Apart, from appreciable radiation efficiency of 84.9% and 81.7% for Wi-Fi and 72.2% for Wi-Max for LTA and 91% for Bluetooth for RTA, both the antennas show excellent mutual isolation (more than −45 dB) for common band frequency. Both the temples of the spectacle antenna have been simulated, fabricated, and tested. Further, the SAR behavior is also investigated, for measurement purpose, liquid phantom is created. It has been found that the measured and simulated results are in good agreement and they satisfy Europe and IEEE standards.
