1. There are 5 dipoles located along the z axis. The current distribution along the z direction is given by where I(z) = To cos(kL/2) 2 J= Σ 21(z-nd), n=-2 0; for z <-L/2, cosk (z L/2); for -L/2<z <L/2, 0: for z > L/2. (a.) What is the magnitude of the current feeding each dipole, (b.) What is the total current feeding the array, (c.) What is the spacing (in terms of wavelength, λ) between dipole feed points (i.e., center of dipole), (d.) Determine the overall length (λ units) of the array. (e.) Calculate the array pattern assuming isotropic (not dipole) radiators, (f.) Assuming the dipole pattern g(0) = sin 0, calculate the radiation pattern. 1. There are 5 dipoles located along the z axis.
