On-body radiation of 3D-printed fold cylindrical helix (FCH) wearable antenna

Low-profile, power-efficient antennas are required for body-worn devices applicable for long-term healthcare monitoring. The paper is focused on the fabrication of fold cylindrical helix (FCH) antennas, and measurement of their performance on the human body. The study considers one-element and two-element FCH arrays. It is found that the fabricated FCH antenna can excite the same on-body propagation within a compact size. The simulated two-element FCH array can achieve a higher gain and its on-body radiation performance is improved over the single FCH.
