DESIGN OF WEARABLE ANTENNAS FOR 5G APPLICATIONS

Design for wearable micro strip antennas which operate at frequencies of 3.5 GHz and 28 GHz which falls under the sub-6 GHz spectrum and mm Wave spectrum of the 5G frequency bands respectively, has been proposed in this article. The antennas are mounted on a polycarbonate substrate of dielectric constant 2.57, thickness 0.5 mm and dielectric loss tangent of 0.0069. Antenna 1 resonates at a frequency of 3.466 GHz and its operating bandwidth ranges from 3.445 to 3.487 GHz (1.2%) with a peak gain value of 8.018 dBi and Antenna 2 resonates at a frequency of 28.36 GHz with its operating bandwidth ranging from 27.604 to 29.094 GHz (5.2%) and attains a peak gain value of 8.886 dBi. Within the operating bandwidth ranges of both the antennas the gain is almost constant and hence the proposed design can be used in various sectors such as healthcare, sports military etc
