Wearable Tri-Band Antenna for Mm-Wave

Abstract

In this research, we introduce a compact wearable patch antenna designed for smartwatches. The antenna operates in millimeter wave frequency bands, making it suitable for wireless communication applications. In this study, a coplanar waveguide (CPW) technology is used to maintain a small size. The suggested antenna is inked upon an RT Duroid 5880 flexible Roger substrate, which has a standard 0.25mm thickness. The antenna is 4 x 3 x 0.25 mm overall. The recommended antenna’s overall radiation efficiency is more than 85% and has gain values of 5.3dB, 7.57dB, and 9dB for 28GHz, 38GHz, and 60GHz frequencies, respectively. Because of this, the suggested tri-band antenna is therefore perfect for various application.
