Project Summary

The project is about the antennas used in wearable smart devices, early research on antennas in wearable smart devices focused on Bluetooth or WIFI antennas such as dual WIFI antennas on smart glasses and multi Bluetooth antennas. Unfortunately, these early wearable smart devices only configure Bluetooth or WIFI antennas and can only indirectly connect to 3G/4G mobile networks carried on mobile phones through Bluetooth or WIFI.

In this Project, the integrated design of antennas for glasses is proposed The most important highlight of this design is that it makes full use of the limited three-dimensional space structure provided by glasses and achieves the perfect combination of antenna and glasses in the physical structure. The antennas for 5G communication are arranged on two glasses frames, and on two glasses legs. In this way, we can make full use of the space provided by the glasses to design antennas and try to ensure that there is a certain distance between the antennas so that the performance of antennas can be guaranteed.

Project Objectives

The objectives of this proposed project are:

• To design antenna in sub 6GHz band for 5G communications.
• To efficiently use three-dimensional space provided by the glasses frame.

Project Implementation Method

The project is being designed and simulated using the software ANSYS HFSS, the design of geometry is almost completed and now we are working on the simulation and improvement of the results.  

After completing the objectives and achieving the best results the sample will be forwarded for fabrication.

The substrate of the sample will be fabricated on dielectric material i.e. FR4 substrate. The antennas and ground plane will be fabricated on a copper sheet.

In addition, active materials such as inductors and capacitors will also be used in the fabrication of the prototype. the antenna will be fed by a coaxial feeding mechanism.

After completing the fabrication process the results of the sample will be tested with the help of a portable vector analyzer (VNA).

Benefits of the Project

Smart glasses are the future technology it has wide spread applications in the industrial feild as well as in the security sector.

Firstly, With 5G antenna of smart glasses, the available information at the work site is easily transferred to the controlling and central or distributed monitoring stations. The process of information exchange, information sharing is done very quickly and even can be stored for future reference

The second important benefit of smart glasses is that it has potential to scane the image through its builtin camera and can show the related data about the image on the head mounted display

Technical Details of Final Deliverable

The proposed antenna is designed for smart glasses and it will be resonating on the band of sub 6GHz for 5G communication.

The overall structure of glasses is designed the same as the simple glasses frame compatible for every human being. the frame will be fabricated on the dielectric material i.e FR4 substrate two capacitors of 0.4pf and two inductors of L1=2.5nH and L2=1.0nH is used in the design. the complete integrated design of the antenna is fed by the coaxial feeding mechanism.

Lastly, a portable vector analyzer will be used to test and analyze the results of the fabricated prototype
