[All 312-38 Questions]

Which antenna's characteristic refer to the calculation of radiated in a particular direction. It is generally the ratio of radiation intensity in a given direction to the average radiation intensity?

Show Suggested Answer Hide Answer
Suggested Answer: C

Directivity of an antenna refers to the measure of how concentrated the radiation emitted is in a single direction. It is defined as the ratio of the radiation intensity in a given direction from the antenna to the radiation intensity averaged over all directions. In simpler terms, it is the calculation of radiated power in a particular direction compared to the average radiated power in all directions. This characteristic is crucial for antennas designed to transmit or receive signals in a specific direction, making it an essential parameter for many communication systems.

Hold on, I'm still trying to figure out if the antenna has any plans for world domination. Asking for a friend, you know.

Hmm, I was thinking Polarization, but I think Claribel has the right idea. Directivity sounds like the correct answer here.

That makes sense, Elfrieda. Directivity could be the correct answer too.

I'm not sure, but I think it could also be C) Directivity, as it relates to the intensity in a specific direction.

I'm pretty sure it's C. Directivity, since that's all about the radiation pattern and how the antenna concentrates the energy in a particular direction.

I agree with Honey, because radiation pattern is about the direction of radiation.
