Question 1 of 27070

Which of the following best describes the polarization of a satellite signal?

🔍 Key Concepts

• Electromagnetic waves have both an electric and a magnetic field that are at right angles to each other and to the direction of travel • Polarization in communications usually refers to only one of these two fields • Satellite communications often use linear (horizontal/vertical) or circular polarization

💭 Think About

• When engineers talk about polarization (horizontal, vertical, circular), which part of the wave are they actually tracking: the electric field or the magnetic field? • Look at the options that mention antennas: are they defining polarization itself, or just how an antenna might be oriented to match it? • Among the choices, which one gives a definition that would still make sense even if you did not mention any specific antenna type?

✅ Before You Answer

• Be clear on which field defines polarization: electric vs magnetic • Separate the definition of polarization from how antennas are physically aligned to receive it • Ask: which option is a general definition that would apply to any satellite system, regardless of antenna design?
