Answer» The correct answer is (a) Circular polarization Explanation: In helical antenna, the diameter and pitch of the helix are comparable to a wavelength. The antenna FUNCTIONS as a directional antenna radiating a beam off the ENDS of the helix. It RADIATES circularly polarized radio waves. These are USED for satellite communication.
