Question B-006-009-004

If a parasitic element slightly longer than a horizontal dipole antenna is placed parallel to the dipole 0.1 wavelength from it and at the same height, what effect will this have on the antenna's radiation pattern?

Correct Answer

A major lobe will develop in the horizontal plane, from the parasitic element toward the dipole

Explanation

A slightly longer element placed behind acts as a reflector, reinforcing the signal in the forward direction (away from the reflector).
