Electromagnetic Analysis and Experimental Validation of the LOFAR Radiation Patterns

Figure 7

LBA-outer array voltages at different frequencies: (a) 32, (b) 44, (c) 57, and (d) 70 MHz. Panels (a) and (b) show the full-wave array pattern computed with the embedded element patterns (black curve, FW) and the array pattern based on the array factor (grey curve, AF). Panels (c) and (d) show the (percent) differences between the two array patterns.
