Abstract
This paper proposes human body effect and bending analysis of a fully flexible wearable antipodal Vivaldi antenna for 5G n77 and n78 bands with compact size of 33 × 33 mm2 (length × width), resonating at 3.5 GHz. The flexible polyester substrate with a dielectric constant (ɛr) of 1.34 and loss tangent (tan δ) of 0.005 has been used for the design. The antenna is bent in both x- and y- directions, with different angles. On-body analysis was performed on different body parts using homogeneous human model. The analysis was performed extensively using reflection coefficients of the studied antenna structure.
