Eccouncil Exam 312-38 Topic 1 Question 99 Discussion

Actual exam question for Eccouncil's 312-38 exam

Question #: 99
Topic #: 1

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?

ARadiation pattern

BPolarization

CDirectivity

DTypical gain

Show Suggested 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.

I believe the correct answer is A) Radiation pattern, as it specifically mentions calculation of radiated in a particular direction.

Haha, typical gain? That's a good one. I bet the exam writer was giggling to themselves when they came up with that as an option.

I bet the exam writer is trying to trick us with this one. Probably the wrong answer is the one that sounds the most technical, like D, typical gain.

Yeah, I agree. Directivity sounds more like the correct answer.

I think you're right, it's probably not D, typical gain.

The question says it's the characteristic that refers to the calculation of radiated power in a particular direction. Gotta be C, directivity. Easy peasy.

I'm not sure, but I think C) Directivity could also be a possible answer.

I was thinking B, polarization, but now that I think about it, that's more about the orientation of the electric field. Directivity makes more sense.

Hmm, this one's a tough one. Gotta be C, directivity. That's the ratio of the radiation intensity in a particular direction to the average intensity, right?
