The Design Of Circularly Polarized Cylindrical DRA for 5G Applications

Week 6 (FYP2) Date: 26/8/2019 Title: Parametric study  Based on the results that was collected during the first simulation of the antenna. A parametric study was conducted to get a better improvement of the antenna. in order to get a better improvement of the antenna, the parametric study and the size of the DR must vary to make sure that the best obtained result from the antenna was obtained. The figure below shows the parametric study that has been done with various size of the DR.  From the parametric study that was done, the selected size of the DR is at 5.4 mm in radius. 

Week 5 (FYP2) Date: 21/8/2019 Title: FYP Briefing The briefing was conducted at 3pm at TTL 2. The briefing was meant to give some explanation to all Final Year Project student. The briefing is about : Result & Conclusion (Chapter 4), Conclusion (Chapter 5) and abstract in thesis writing.

Week 4 (FYP2) Date: 12/8/2019 Title: Results Obtained From the Simulation With the simulation of the antenna finished, a simulated results from the simulation of the antenna will prove to see if the design of the antenna is suitable to be used as the proposed design of the antenna in which it must be at 28 GHz. S-parameter for the Antenna In the figure above it shows the s-parameter of the antenna to see if the antenna have obtained the desired 28 GHz. Radiation Pattern of the antenna Axial Ratio of the Antenna The Axial Ratio of this design of the antenna determines that this antenna is circularly polarized as the axial ratio is under 3dB at 28 GHz.

Week 3 (FYP2) Date: 5/8/2019 Title: First simulation Done for the Antenna Once the material and methods have been chosen for designing the antenna. A simulation must be made to make sure that the design of the antenna was suitable for the target of getting the antenna to be at 28 GHz. The simulation of the antenna is made using the CST simulation software for antenna design.  With the figures shown below are the simulation of a design of the antenna using the CST software showing the stacked DR and the power divider.  Power Divider section of the antenna Top view of the stacked DR Blue square is the slot fed method for the antenna
