Two-element array. A wire antenna is placed perpendicularly above the ground. The wire is 3 m long and is used in conjunction with a transmitter which operates at 100 MHz.
(a) Find the radiation pattern of the antenna.
(b) For a current I = 1 A, find the radiated power of the antenna.
(c) Suppose the wire is adjusted so that the antenna is exactly 1.5 wavelengths. What are now the radiation pattern and radiated power. Compare with (a) and (b).
