a) What is the difference between Beam-Width and First Null Beam-Width?

b) A 70% efficient antenna is having a radiation resistance (Rr) and loss resistance (RL). Calculate the ratio between (Rr) and (RL).

c) Calculate the maximum effective aperture of an antenna operating at a wavelength of 0.5m and has a directivity of 250.
