Abstract :
In this paper, we present three cellular antenna designs for the smart watch application by using the metal watch belt. Our proposed antennas can cover cellular bands down to 700 MHz and up to 2.7GHz. Their performance in the free space and user cases are measured and discussed. The SAR evaluation guideline from FCC is also introduced and SAR measurement results are shown.
