Project Title

Design and analysis of Meta-material inspired wearable antenna for Fifth Generation communication

Project Area of Specialization Information & Communication TechnologyProject Summary

Antenna design for wearable technologies is a challenging task due to the body being in the near-field of the antenna. For suitable wearable antenna design needs omnidirectional radiations, directed away from the human body. Ideally, the radiation should have no side and back lobes. When the antenna is placed in close proximity of the human body, so, due to the non-homogeneous structure and complex permittivity of the human body tissue overall performance of the antenna is greatly affected. Besides, bending and stretching consequences the radiation in human body tissue is absorbed and therefore, resulting in an increase in Specific Absorption Rate (SAR). For higher frequencies, the consequences will be much severe compared to lower frequencies. In order to enhance the overall performance of the antenna and also to reduce the radiation towards the human body, currently, a metamaterial ground plane has been introduced. Therefore, there is a need to design an antenna backed by a metamaterial surface and to compare the overall performance with the real ground plane.

 Project Objectives

• Design and analysis of (38 GHz) ,5G antenna for wearable application.
• Design and characterization of single-band metamaterials.
• Design and analysis of (38 GHz), 5G antenna with metamaterial surface.
• Performance comparison of the proposed antenna with and without metamaterial surface.
• Study the performance of the antenna on the human body (Flat and bent) with and without metamaterial surface.
• Specific Absorption Rate (SAR) analysis. 

Project Implementation Method

All simulations and the optimization process are performed using CST or HFSS, an industry-standard software simulator which is based on Finite Integration Technique (FIT) that is equivalent to Finite Difference Time Domain (FDTD). The following steps are involved; Selection of Materials. The selection of materials includes selecting such materials that are low loss i.e. having low loss tangent also easily available etc. Designing of 5G wearable antenna with metamaterial surface. To design the wearable antenna, we will use different techniques such as slotting, different feeding techniques, and metamaterials, etc. Comparison and result validations.

 Benefits of the Project

1)         A wearable antenna can track our daily activities.

2)         It can be used for Biomedical and Telemedicine applications. Where physician can track their patient activities and monitor their condition remotely.

3)         An important characteristic of such antennas is their insensitivity to dielectric coupling and user movements, which is linked to physical factors such as deformations, varying mounting locations, and body morphologies.

4)         Wearable technology, a wireless body sensing system is now able to support various internet of things (IoT) applications such as,

?         High-speed communication

?         Tracking

?         Health monitoring

?         Radiofrequency identification
