What is the Optimum operation of a space diversity system in the antenna separations, if R = effective earth radius (meter) and L = path length (meter) is given? Correct Answer S = 3λR/L

Key Points
  •  Space diversity systems normally employ two vertically-spaced antennas at one end of a link.
  • Such configuration with standard spacing are usually sufficient effective against the effects of multipath fading and distortion.
  • For optimum operation of a space diversity system the antenna separation should be;

 

S= 3λR/L

here, R= effective earth radius ( meter )

L = path length ( meter ) 

Additional Information

 Increasing the spacing of the antennas has been suggested as a way to more effectively combat the effects of beam spreading and associated surface multipath fading.
