Antenna design using CST suite to obtain s11

I am looking for a freelancer who can design an antenna using the CST suite to obtain s11 measurements within the frequency range of 1-5 GHz.

Skills and Experience Required:
- Proficiency in using the CST suite for antenna design
- Expertise in working with frequencies ranging from 1-5 GHz
- Knowledge of antenna design principles and techniques
- Familiarity with Vivaldi antenna dimensions and their implementation in the design process

The project does not require optimization, but the freelancer should be able to efficiently design and simulate the antenna to obtain accurate s11 measurements. The chosen dimensions for the design are Vivaldi.


Also, Antenna design in microwave imaging to detect breast tumor.
Antenna will be designed with the phantom to detect breast tumor.(varying tumor sizes)
Simulation will be done.
Studying s11 parameters for different sizes of the tumor.
