I am trying to get percentage radiation efficiency of leaky wave antenna. Could anyone tell me the steps for the same?
Please Follow these steps:
1. Define the farfield monitor for the desired frequency.
2. Plot the 3D farfield pattern it will give you both radiated as well as total efficiency in dB
3. Use the formula to convert dB to percentage
p = (10 ^ X/10) *100
Where X efficiency in dB
This one is in linear (dB); you may change it by multiplying the value at the desired frequency *100.
Dear Sadhu,
The radiation and total efficiency of the antenna in CST can be seen from the 1D results section plot. As plot mentioned by Ahmed Jamal Abdullah Al-Gburi , you simply take the linear scale value and multiply by 100. So, you will get the efficiency of any kind of antenna.
Hope you find the answer.
Thanks.

You can try this. Just copy the dB values and use the following formulae.
x(in dB) = 10*log10(p), where p is in % with scale 0-1. To get p, divide x by 10 and take the antilogarithm of the answer, you will obtain p with scale 0-1, you can then multiply this p values by 100 to obtain the percentage scale 0-100%
i.e p = 10^(x/10) where p is with percentage scale 0-1. p=(10^(x/10))*100 where p is with percentage scale 0-100. Hope it works.
