Abstract
This paper presents a detailed on-body performance analysis of wideband wearable antenna for 5G applications. The proposed design (antipodal vivaldi antenna structure implemented on a polyimide and polyester combined substrate) showed excellent performance in free space with a bandwidth of 910 MHz (covering 5G-NR Bands like n48, n77, and n78). Afterward, since the antenna is wearable, it is required to perform efficiently near the human body. Consequently, a detailed on-body analysis was conducted, and the antenna radiates efficiently. SAR has been assessed to make sure of the safety of the wearer; throughout the entire bandwidth, the SAR value remains within the safety regulation of ICNIPR, threshold 2W/kg per 10g of tissue.
