Unformatted text preview: with I being a constant and α some real number (note that this is not the usual current distribution). Find the farzone electric and magnetic fields radiated by this antenna (in spherical coordinates). You may use the results of problem 1. (4) Find the farzone electric field of a linear wire antenna l =30 cm long at two frequencies: f = 1 GHz and f = 1.5GHz. Plot the antenna power pattern at both frequencies in rectangular (not polar) form. By inspecting these plots, determine the sidelobe levels in negative dB and the halfpower bandwidth (HPBW) in degrees. Indicate both quantities in the plots (Note: assume the usual sinusoidal current distribution given in class for a finite length wire antenna)....
