Question

Which type of polarization is found in parabolic reflector?

(a) Right-hand Circular

(b) Linear

(c) Depends on the feed

(d) Left-hand Circular

I had been asked this question in a national level competition.

I want to ask this question from Types of Polarization topic in chapter Radiation, Baluns & Polarization of Antennas

Answer 1

Right choice is (c) Depends on the feed

For explanation: The parabolic antennas take the polarization of the feed. The linear polarization takes place in the monopole dipole. In the Dipole also a linear polarization takes place. In helical, circular loop antennas we can find the circular polarization.
