A thin center-fed dipole antenna of length L = 50 cm is fed with input current 100 mA at 30 MHz. The antenna is situated on the Y-axis in free space.

(a) Calculate the power radiated by the antenna.

(b) Obtain expressions for the radiated fields.

(c) Specify the results of (b) for the principal planes and draw the radiation field patterns.

(d) Determine the directivity function. (e) Calculate the maximum radiation power density 1-km away from the antenna.

(f) If there exist another dipole antenna with the same configuration placed at the x-axis, find the radiation pattern at far-field region
