T9A03

How is the polarization of an antenna described?

  • A.By the shape of the driven element
  • B.By the orientation of the electric field (correct answer)
  • C.By the orientation of the magnetic field
  • D.By the direction of radiation

WhyAn antenna's polarization is described by the orientation of the electric field. An antenna's polarization is described by the orientation of the electric field it radiates, vertical, horizontal, or circular, answer B. It isn't described by the driven element's shape (A), by the magnetic field's orientation (C, which is always perpendicular to the electric field rather than the defining reference), or by the direction the signal radiates (D), which is a separate property from polarization.
