Wearable technology in the recent years has gained popularity worldwide and has encouraged researchers to initiate studies in field
of material science, electromagnetics, electronics and communication and so on. Wireless body area network (WBAN) has attracted
many such applications be it a body worn device [1]–[4] or implanted [5]–[8]. The major challenges faced by the antennas in this
technology are high dielectric losses offered by the antenna platform which is a human body in this case. Many wearable antennas
have successfully overcome the issue with the use of multi-layer antennas which significantly increased the gain and also improved
the Front-to-back ratio.
