We find the total power emitted by a helical antenna and the maximum directivity. This question is taken from GATE 2016 SET 1 Electronics and Communication paper (Question 55). Essential video for engineering fundamentals.
To find the total power emitted we surface integrate the radiated power over the surface and then find the maximum directivity.
