Title: Project Discussion with Supervisor

After finishing with the initial design of the DRA I have advanced a bit in the DRA design with designing a DRA that can produce circular polarization. After finishing the initial design i have made a further research in which i can advance the design of the antenna to suit the requirements on making it circularly polarized and can be used for 5G applications. With doing the research i have found out that in designing the antenna a few different method can be used to generate circular polarization in which by changing the position of the feeding for the antenna and shifting the feeding can also generate circular polarization. But my idea was to combine a conformal trip feeding and adding a 90 degrees microstrip feeding in order to generate the circular polarization. 

Here i attach the designs that i have improved from the initial design.

The above picture shows a slotted DR design in which is used as an idea of the antenna design and it is feed with a microstrip.

With the design above i managed to get the s11 value to be below -10dB. with further discussion with Dr Ismail i was able to come up with a better design of the antenna and producing the Circular Polarization.

The latest design of the antenna was able to produce circular polarization with the design being having a microstrip feeding method and conformal strip attached to the DR thus making it produce circular polarization as will be shown in the results below.
