Comparative Study of Plier and Moon Shape Antenna for Best Bandwidth

Abstract

Due to their appealing qualities and potential for allowing portable, wireless communication and sensing that is light, flexible, affordable, and easy to use, wearable antennas have gained a lot of interest in recent years. When applied to various body parts of a human, such antennas must conform, hence they must be implemented with flexible materials, with a low-profile design. In the end, these antennas are required to have the ability to function in close proximity to a human body with the least amount of deterioration. Certain conditions make the design of wearable antennas difficult, especially when taking into account factors like their size compactness, body coupling and structural deformation effects, and complexity of manufacture and precision. Although their severity varies slightly between applications, the majority of these problems are present throughout the setting of body-worn implementation.A Plier Shape Novel wearable antenna for wireless communication was designed and simulated in CST software to achieve a body area network with better bandwidth and a resonant frequency of 3.224 GHz. The materials used for the textile are denim as the substrate of the antenna with a dielectric constant of 1.7 and the conductive element as copper tape. The board size is 61*51mm2. The bandwidth of the proposed antenna is 129.72% for the frequency range of 2.6 GHz to 12.2 GHz, which is considered to be the optimal bandwidth for the antenna.
