← TechnologyWhich outcome occurs when a microwave antenna array's elements fail calibration?
A)Null steering becomes less precise✓
B)Higher side-lobe energy suppression results
C)Beamwidth decreases due to supergain
D)VSWR at the input port decreases
💡 Explanation
Null steering precision degrades because element phase errors induce unintended beamforming via the sidelobe leakage mechanism, therefore nulls deviate from target directions rather than enhancing sidelobes, because of specific phase errors.
