Why a helical antenna is used for satellite tracking?

(a) because of its circular polarization

(b) because of its broad bandwidth

(c) because of its low bandwidth

(d) because of rectangular polarization

This question was posed to me at a job interview.

My doubt is from Noise in AM topic in section Noise of Analog Communications

The correct choice is (a) because of its circular polarization

Explanation: A helical antenna generally consists of a conducting wire which is wound in the form of a helix. It generally exhibits circular polarization due to which it is mostly used for satellite tracking.
