Morphology
The phrase is compositionally built from 'major' (main, primary) + 'lobe' (a directional region of higher signal strength), so its meaning as the principal or strongest radiation/reception lobe follows directly from the constituent meanings. Although technical, a B1 learner who knows both words can readily infer that 'major lobe' refers to the main/primary lobe in the antenna pattern.
Etymology
The noun major lobe comes from the picture of a shape with rounded parts called lobe and major meaning the largest or 'main' one. So the major lobe is the biggest part of an antenna's signal pattern and points where the signal is strongest.
