Table 1 Electrical performance comparison between simulation and experiment results

From: Effect of Facet Displacement on Radiation Field and Its Application for Panel Adjustment of Large Reflector Antenna

Performance	A₀	B₀	Error	A₁	B₁	Error
Gain (dB)	52.84	52.23	0.61	52.21	52.00	0.21
HPBW (°)	0.390	0.380	0.01	0.48	0.49	0.01
Left SLL (dB)	−14.33	−14.54	0.21	−17.3	−17.8	0.5
Right SLL (dB)	−14.33	−14.18	−0.15	−13.85	−12.53	−1.32

Note: A₀ and B₀ are simulation and experiment without displacement. A₁ and B₁ are with 3 mm displacement. HPBW means half power beam width. SLL means side lobe level
