Question

Tilt angle of the elliptic polarization with respect to horizontal is ____________

(a) τ=\(tan^{-1}(\frac{a_{vertical}}{a_{horizontal}})\)

(b) τ=\(\frac{a_{horizontal}}{a_{vertical}}\)

(c) τ=\((\frac{a_{vertical}}{a_{horizontal}})\)

(d) τ=\(tan^{-1}(\frac{a_{horizontal}}{a_{vertical}})\)

The question was posed to me in final exam.

Question is from Types of Polarization topic in portion Radiation, Baluns & Polarization of Antennas

Answer 1

The correct option is (a) τ=\(tan^{-1}(\frac{a_{vertical}}{a_{horizontal}})\)

For explanation: The two properties of ellipse that relates to the polarization are — eccentricity and tilt or inclination angle with respect to horizontal. Tilt angle of the elliptic polarization is given by

τ=\(tan^{-1}(\frac{a_{vertical}}{a_{horizontal}})\)
