Inverted V dipole

[Rus 1]

Hi guys! 
I'm working on a spacecraft deployable antenna for the 300 - 400 MHz band. 
I found a good article on the subject of vibrator antenna and simulated it. I have encountered two problems:
1. I was not able to get a better VSWR than is shown in the figure. Maybe someone can optimize it better than me?
2. My CST does not show the axial ratio. How to solve this problem? 
Thanks in advance!

Hi buddy...!!!!

,,,what version of CST do you have...???
,,,can you post the CST file..??

Hi Admin!!
I have the 2023 version. 
Yeah, sure. Here is my .cst file of my V-inverted dipole

,,,these would be the results...

 

to see the axial ratio in CST, you should look at "Farfields" section in the simulated results... there should be a drop down list after simulating the design.

if you click on that drop down list you should be able to see the axial ratio plot...

The default plot is in 3D format, if you want to plot it on polar form, you need to right click on a farfield result and select "Far field plot properties", In the "General" tab select "polar" for the "plot type" and choose the values for "Theta" & "Phi" according to the orientation of your design. Then select "apply" to see the results
