A source has a radiation intensity pattern given by U=UM sin θ. The directivity of the source with this power pattern is:

A source has a radiation intensity pattern given by U=UM sin θ. The directivity of the source with this power pattern is: Correct Answer 1.27

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 1.27.
