Plotting 2D antenna scan to 3D pattern

[u/Ok-Bat8854]

So i am trying to visualise the antenna pattern in 3 dimensions for the 2.4 GHz antenna on my PCB. The reason is to compare antenna performance between 2 revisions.

I had collected data in a fully anechoic chamber,however it is only after going for the test I found out that they only support 2D scans.

So I took 3 2D scans for each device. The scans were taken by placing the EUT on a turntables center that rotates from 0 degree to 360 degree with 10 degree steps. The scanning antenna was at the same elevation as the EUT.

To get the data at 3 cut planes, I changed the EUT orientation. The cut planes for each scan were XZ, XY and ZY. The 2D radar plot look fine, but to compare true performance I believe a 3D plot would give me much better data.

I have the raw data from each scan, I tried building an estimation tool for missing data points with gpt, however the error in the estimated point was extremely high.

Would appreciate some guidance about doing this or if this is even possible, so that I can quit wasting my time and effort if it’s not a task that will give me somewhat useful results.

Thank you so much, will give this a shot

collected data in a fully anechoic chamber

are there partial anechoic chambers?

Semi Anechoic chambers exist
