How do i increase the bandwidth of the attached antenna to cover the 300MHz till 1000MHz frequency band

i am designing a base station antenna with the bow tie antenna and i cant get the bandwidth to stretch over the desired frequencies, I am attaching my two attempts to this question. Thank you

    Hi Chinaza,

    What is causing it to fail? Are you getting any error messages?

    Hello Torben,

     

    I am not getting any error messages, the antenna is resonant at a smaller range of  frequencies but i need it to work over a wider range of frequencies, i attached the two files.

    Hi Chinaza,

    That sounds like a case for optimisation. Maybe take a look at User Example A.6 to understand how optimisation works in Feko. Above all, you would have to redesign the model using variables. The geometry must be parametric so that OPTFEKO can change the variables in the course of the optimization.

    If you need help with this, I would recommend creating a support ticket on Altair One.

    Hello, sorry for getting back to you late. thanks for the advice, I learnt how to use optimization, and i have succeeded in completing the design of the antenna with appropriate bandwidth. I am very grateful.
