Question 1

What is a phased array antenna?

Accepted Answer

An antenna with electronically steered beams

Answer

A phased array antenna consists of multiple radiating elements whose phases are electronically controlled to steer the beam without moving the antenna.

Question 2

What is the primary advantage of MIMO (Multiple Input Multiple Output) antennas?

Accepted Answer

Enhances data rates and signal reliability

Answer

MIMO technology increases data transmission rates and improves signal reliability by using multiple antennas to send and receive data simultaneously.

Question 3

Which type of antenna is commonly used for satellite communications?

Accepted Answer

Parabolic reflector antenna

Answer

Parabolic reflector antennas are widely used in satellite communication due to their high directivity and ability to focus signals over long distances.

Question 4

What is the main benefit of a fractal antenna?

Accepted Answer

Operates efficiently over multiple frequency bands

Answer

Fractal antennas are designed with self-similar patterns, allowing them to operate efficiently across multiple frequency bands while maintaining a compact size.

Question 5

Which advanced antenna technology is used in 5G networks for beamforming?

Accepted Answer

Massive MIMO

Answer

Massive MIMO technology allows 5G networks to use beamforming, directing signals toward specific users to improve data rates and efficiency.
