What is a phased array antenna?
Answer: An antenna with electronically steered beams
A phased array antenna consists of multiple radiating elements whose phases are electronically controlled to steer the beam without moving the antenna.
What is the primary advantage of MIMO (Multiple Input Multiple Output) antennas?
Answer: Enhances data rates and signal reliability
MIMO technology increases data transmission rates and improves signal reliability by using multiple antennas to send and receive data simultaneously.
Which type of antenna is commonly used for satellite communications?
Answer: Parabolic reflector antenna
Parabolic reflector antennas are widely used in satellite communication due to their high directivity and ability to focus signals over long distances.
What is the main benefit of a fractal antenna?
Answer: Operates efficiently over multiple frequency bands
Fractal antennas are designed with self-similar patterns, allowing them to operate efficiently across multiple frequency bands while maintaining a compact size.
Which advanced antenna technology is used in 5G networks for beamforming?
Answer: Massive MIMO
Massive MIMO technology allows 5G networks to use beamforming, directing signals toward specific users to improve data rates and efficiency.
What is the key advantage of a dielectric resonator antenna (DRA)?
Answer: Improves signal loss at high frequencies
Dielectric resonator antennas provide high radiation efficiency and reduced losses, making them suitable for high-frequency applications.
