A dipole with a length of 0.5A was positioned with its center at the origin and operated at a frequency of 1 GHz. It is supplied with a current (lo) of 0.2 A. The antenna is aligned in the z-axis direction. (a) Find the power densities at r = 100 m, 0 = 90-, $ = 0². (b) Find the power densities at r = 50 m, 0 = 45-, $ = 45- A dipole with a length of 0.5A was positioned with its center at the origin and operated at a frequency of 1 GHz.
