What is the far field of an antenna?
Pick an answer to check it.
Answer: D. The region where the shape of the radiation pattern no longer varies with distance
The far field is the region where the shape of the radiation pattern stays the same no matter how much farther away you go. Closer in, in the near field, the pattern shape still changes.
Tip: Far field: pattern shape stops changing.
