Yes meshing can influence the result but it consumes a lot of time and RAM and processor power as well. This video is only for instructional purpose and so I used default mesh setup that is quick for simulation
Sir, can you kindly help me by providing the values of r and h to design this antenna with resonance frequency of 3 GHz? I am badly need of this values.
@@tensorbundle Can the software do this for you, if you make a certain shape, it can tell you what size is needed for target frequency, or you have to do all calculations yourself?
Thank you mr.. Hasan
Thank you very much. I think if you change the solver or increase the mesh density, this result will be changed.

could you tell me that , how did you calculate the feeding length at 40mm

port extension coefficient is not seem for me please help
How I can contact to you
Sir the formula you describe is only for CDRA or can be implemented on RDRA and SDRA?
only for CDRA..RDRA/SDRA have different formula.
Can you design one for a specific frequency, or is there equation for what dimensions to use to get a certain frequency? Thanks
Design equation is already mentioned in the video

@@phild.1122 yes, it is doable in MATLAB
How to increase gain in CDRA
Sir how to calculate gain ? What should be the value of the gain?
The gain can be seen in 17:43 minutes of the video. It is found to be 6.77 dBi at 4.1 GHz
