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? %3D
