A Wideband Octagon-Shaped Patch Antenna for Wearable Devices

In the present work, a compact octagon-shaped MPA is developed for wearable applications. The dimension of the antenna is 36mm × 28mm × 0.8mm, including a partial ground plane. The resonating frequency of antenna elements is 2.57GHz band, which covers Industrial, Scientific, and Medical (ISM) unlicensed, LTE, and WLAN bands. The results are calculated by simulation in HFSS and then compared with available literature. The result shows that the antenna bandwidth is 460 MHz at the desired frequency of 2.57GHz with a gain of 3.35 dBi. The proposed antenna can be suitable for applications such as IoT, portable devices, wearable gadgets, etc.
