A radio station has two antennas. The antennas are a distance d apart, where d equals half the broadcast wavelength. The antennas are driven in phase with each other. Let the x-axis be the line that runs through the two antennas. The angles are all measured counterclockwise from the +x-direction. (For the following, assume an observer is positioned a distance D far from the midpoint of the antennas, so that
D ≫ d.)

Sources A and B emit long-range radio waves of wavelength 310 m, with the phase of the emission from A ahead of that from source B by 90°. The distance rA from A to a detector is greater than the corresponding distance rB from B by 150 m. What is the magnitude of the phase difference at the detector?
Two identical short dipole antennas are driven in phase with each other with equal strength and
emit readiation at a wavelength of = 0.1 meters.
One antenna is oriented in the y-direction and is located at (x,y,z) = (0,0,0). The other antenna
is oriented in the z-direction and is located at (x,y,z) = (d,0,0) where d > 0.
What is the smallest value of d for which the radiated far-field at a point (x.y,z) = (X, ,0, 0), x,>>
d, and A, is circularly polarized?
What happens to the polarization if d is now doubled?
