For the lobe width, which of the following descriptions is correct is (). (Select 3 Answers)
A) Within the range of the main lobe, the power density relative to the maximum radiation direction is reduced by half (3dB) Angle and B) The narrower the lobe width, the better the directivity, the longer the radiation distance, the stronger the anti-interference ability and C) The pattern usually has two or more lobes

Wait, are we sure about B? Sounds a bit too simplified.

I agree with B, narrower lobes do improve directivity!

A is definitely true, 3dB is the half power point.

I vaguely recall that the half power angle is crucial for signal reception, so option D might be correct, but I need to double-check that.

I practiced a question similar to this, and I feel like option C could be misleading since not all patterns have multiple lobes.

I think option B sounds right because narrower lobes usually mean better directivity, but I'm not completely confident about the anti-interference part.

I remember something about the 3dB point being important for lobe width, but I'm not sure if it's specifically about the main lobe.

I'm a bit confused on this one. The question mentions the analyst's roles, but I'm not sure how that relates to the ability to import contact lists. I'll need to think this through carefully.

Gotta go with A, B, and C on this one. D is just plain wrong - the signal coverage extends well beyond the half-power points. Maybe the exam writer was napping during Antennas 101.

A, B, and C are right. D is just silly - the signal isn't suddenly cut off at the half-power angle. Antenna engineers have a great sense of humor, don't they?

I believe option D is also correct, as the terminal can only receive signal within the half power angle coverage.

All 3 answers are correct. The lobe width is a critical antenna parameter that impacts performance. I'm surprised D is even an option - that's way too limiting.

A and B are correct. Lobe width is inversely proportional to directivity and range. C is also true, but D is too narrow - the signal can be received outside the half-power angle, just at reduced power.
