Printed Log Periodic Antenna

Started by Rus,

Posted (edited)

Hi everyone!
I work on printed log periodic antenna in 300...400 MHz band and I found out that the theoretical expressions do not give a good result and antenna still needs an optimization.

While optimizing I faced to a problem, that the CST optimizer changes all parameters in the same time so the structure is changed dramatically.

Give me please an advise how to run the optimization of the antenna structure while saving arm's dimensions ratio. Here is the .cst file

Thank you in advance
