Q:What is the difference between analog beamforming and digital beamforming?
Analog beamforming employs phase shifters and combiners in the RF domain.
Digital beamforming processes signals digitally at each element, offering greater flexibility but also higher complexity.
-
Q:What is hybrid beamforming architecture?
The combination of analog and digital beamforming is commonly used in 5G millimeter-wave and satellite communications to balance cost and performance.
-
Q:How to mitigate grating lobes in phased arrays?
Element spacing is less than or equal to λ/2
Non-uniform array layout
Advanced beamforming algorithm
-
Q:What are the challenges faced in designing high-frequency phased arrays (mmWave/THz)?
High path loss → requires high gain and beamforming
Thermal management
Precision manufacturing (strict tolerance for small wavelength)
