CST Tutorial: Cylindrical Dielectric Resonator Antenna in CST

[@manikandanb8072]

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

[@Hadi-zw9mb]

Thank you very much. I think if you change the solver or increase the mesh density, this result will be changed.

[@tensorbundle]

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

Thank you mr.. Hasan

[@fikret8422]

port extension coefficient is not seem for me please help

[@unproductivehours1945]

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.

How to increase gain in CDRA

[@mohammedsalem6085]

How I can contact to you

[@phild.1122]

Can you design one for a specific frequency, or is there equation for what dimensions to use to get a certain frequency? Thanks

[@tensorbundle]

Design equation is already mentioned in the video

[@phild.1122]

@@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?

[@tensorbundle]

@@phild.1122 yes, it is doable in MATLAB

[@hamzaasifkhan8421]

Sir the formula you describe is only for CDRA or can be implemented on RDRA and SDRA?

[@tensorbundle]

only for CDRA..RDRA/SDRA have different formula.

[@sujoysaha5608]

Sir how to calculate gain ? What should be the value of the gain?

[@tensorbundle]

The gain can be seen in 17:43 minutes of the video. It is found to be 6.77 dBi at 4.1 GHz
