1. I need to design and simulate serial feed microstrip array antenna at frequency of 120 GHz.
2. How can I improve the bandwidth (BW) of the serial feed microstrip array to 10% at least?
3. Can you attach an example?

Thanks ,

But I need the technique to improve the BW of serial element feed microstrip array antenna, not the software.
I am using the CST MWS.
