Designing Printed Log-periodic dipole array in CST

Hello. I have this problem. I have thesis Log-periodic antenna. Now a must design this antenna in CST Studio. But i dont have idea how.

I have all calculations for construction of this antenna (Log-periodic). For all calculations i use book Antenna Theory by Balanis. My teacher recommend me this perfect book.

This antenna will be on printed circuit (FR4).

Frequency range is: 700 MHz - 3 GHz.

Do you have some ideas how to start designing in CST? I watched some videos on youtube but i dont find how to design in CST Printed LDPA.

Thank you for you help.
