Anyone here worked on or know of near field antenna measurements?

AI Thread Summary
The discussion centers on seeking assistance with near field antenna measurements, particularly regarding the sampling procedure for creating a plane wave spectrum in one-dimensional planar measurements. The original poster is using Mathcad and is unsure about the number of samples needed for accurate probe field calculations. A participant mentions their experience with near field radio links but requests more details about the setup and specific issues faced. The conversation highlights the need for clarity on sampling techniques in near field measurements. Further insights are expected if more information is provided.

Hi,

Im looking for some one who has worked on or knows the concept of near field antenna measurements.

If there is anyone here I would really appreciate that you reply and answer some of my questions.

I am having trouble with the sampling part for creating my plane wave spectrum.. I am doing my measurements over a 1 dimension planar near field measurement and will be using mathcad.

If anyone knows the topic please reply and ill post more details about my topic.

Thank you

no one?? :(

i just wanted to clarify the sampling procedure..

that is if i am going to calculate over only 1 dimension in planar near field measurement.. then how many samples should i take on the probe field?
 
I don't think I'm the person you're looking for, however I did work with a near field radio link in the 200 - 400 kHz range. Can you describe your setup and the problem you're having in more detail?
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.)
