Q:

A source has a sine squared radiation intensity power pattern. The directivity of the given source is:

A) 1.5 B) 3
C) 2.5 D) 3.5
 
Answer & Explanation Answer: A) 1.5

Explanation: To find the directivity of the given source, the power radiated by the given source is found out by the method of integration. Taking the ratio of the power radiated by the given source to the power radiated by an isotropic source gives the directivity. Following the above steps, the directivity of the given source is 1.5.

Q:

A source has a cosine power pattern that is bidirectional. Given that the directivity of a unidirectional source with cosine power pattern has a directivity of 4, then the directivity of the unidirectional source is:

A) 1 B) 2
C) 3 D) 4
 
Answer & Explanation Answer: B) 2

Explanation: Given the directivity of unidirectional power pattern, the directivity of bidirectional power pattern is half of it. Hence the directivity of the source is 2.

Q:

The expression for pointing vector of an isotropic point source at a distance ‘r’ from the source is given by:

A) P/ 4?R² B) P/4?
C) P/ 4?R D) P×4?R²
 
Answer & Explanation Answer: A) P/ 4?R²

Explanation: The pointing field vector for an isotropic source is given by the expression P/ 4?R².P is the total power radiated y the source. As the distance of the point from the source increases, the magnitude of pointing vector decreases.

Q:

Antennas that radiate energy only in a specified are called anisotropic antennas.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: All physically realizable, simplest antennas also have directional properties. That is, they radiate energy in one direction than in any other direction. Such sources are called anisotropic point sources.
