I have a project where I have to create three antennas in CST according to an article I was given by my supervisor. I have created the three antennas according to the article, but the results (graphs) are not quite the same as supposed to be. There has to be done an optimization or parametric sweep in all the three antennas.

The article and the three CST files that I created so that you can optimize them in order to achieve the required graphs in the article are attached below.

According to my supervisor, after the optization or parametric sweep took place we should be able to achieve the results of Figures 1 (for the antennas 1 , 2 and proposed) and Figures 2 and 3 for the proposed antenna.

Can anyone do the optization or parametric sweep to these 3 antennas so the results of Figures 1, 2 and 3 would be achieved.
