سؤال 360

In which direction does a half-wave dipole antenna radiate the strongest signal?

  1. Equally in all directions
  2. Off the ends of the antenna
  3. In the direction of the feed line
  4. Broadside to the antennaپاسخ درست

توضیح

Current on a half-wave dipole flows along the wire, and radiation is strongest perpendicular to the current and weakest along the wire axis. The pattern is therefore a broadside figure-eight with nulls off the ends, not omnidirectional.
