A Wearable Flexible antenna integrated on a Smart Watch for 5G Applications

Abstract

This paper presents a design of dual-band flexible wearable antenna for modern 5G applications to integrate on a smartwatch. This antenna is a rectangular antenna which the patch and the ground etched on new flexible material is called "ULTRALAM® 3850HT". This material is characterized by thin flexible cores with low and stable dielectric constant, which is a key requirement for high frequency and wearable designs. The dielectric constant ϵr is equal to 3.14, and loss tangent tanδ is equal 0.005 of the ULTRALAM® 3850HT flexible material. The presented antenna is designed to operate at 38 GHz and 60 GHz. The SAR (specific absorption ratio) is also introduced and SAR results will be shown. The presented antenna with and without the smartwatch are simulated using HFSS and CST 2018.
