Hi everyone,

I designed an atenna in CST and i tried in 940 MHz and it gave me what i need. Then i scaled to get the resonant frequency at 433 Mhz but the absoulte farfield for radiation pattern has been changed. i thought when we scale the antenna the result must be the same. anyone knows what i have to do to get the same result?.

Please i need yoour help

What properties of the design did you've scaled? It will be clearer If u can post your original file and the scaled file. It could be your mesh settings. If you scaled only the properties stated in balanis's book on antenna theory you should not get different result.
