Electromagnetic Analysis and Experimental Validation of the LOFAR Radiation Patterns

Figure 9

Measured and simulated array voltage at different frequencies for LBA-inner (a, c, e) and LBA-outer (b, d, f) arrays: (a, b) 44, (c, d) 57, and (e, f) 70 MHz. The top graphs of each panel show the normalized array pattern computed through measurements (grey dashed curve) and simulations (black continuous curve). The bottom graphs of panel show the (percent) differences between the two array patterns.
