Q. 55 Two half-wave dipole antennas placed as shown in the figure are excited with sinusoidally varying currents of frequency 3 MHz and phase shift of 
between them (the element at the origin leads in phase). If the maximum radiated E-field at the point P in the x -y plane occurs at an azimuthal angle of 60° the distance d (in meters) between the antennas is _______.
Answer: (50)
