how to obtain the gain of antenna from antenna pattern file at a particular elevation and azimuth angle.

Hello,

I am trying to obtain a 3D antenna radiation gain pattern using antenna pattern file. The format for antenna pattern file usually is a set of elevation angles ( at 1 azimuth angle) and assosciated gain. And a set of azimuth angles( at 0 elevation angle) and assosciated gain. How do I combine / interpolate the two, to find the gain at any point in space defined by (elevation, azimuth) angle pair using MATLAB?

Any help will be appreciated. Thank you

if you are trying to reconstruct the full 3D pattern from two slices of the pattern. you may find the following example to be useful. this feature is availble in 19a.

Thanks a lot! This is exactly what I have been trying to look for.

Da Huang I tried to run the function patternFromSlices, but matlab says undefined function.

please make sure you have the latest version of matlab, you may need 19a to obtain this new feature from antenna toolbox.

also, there are different algorithm provided to reconstruct your 3D pattern, you may need to explore it a little bit.
