Problem 5: The radial component of the radiated power density of an antenna is given by Wrad = W, a= 4, (cose/r2) a, (W/m) where Ao is the peak value of the power density, 6 is the usual spherical coordinate, and a is the radial unit vector. Determine a) The total radiated power b) The radiation intensity c) The maximum radiation d) The maximum directivity e) The directivity as a function of the directional angles Problem 5: The radial component of the radiated power density of an antenna is given by Wrad = W, a= 4, (cose/r2) a, (W/m) where Ao is the peak value of the power density, 6 is the usual spherical coordinate, and a is the radial unit vector.
