So in the first case I expect the main lobe on the z-axis, while in the second along the x-axis. encratite heresy

"Web17 dec. 2024 · The directivity of an antenna, D, is the maximum directive gain. That is, D = max { G D ( θ, ϕ) } This gives an indication of how well the antenna can focus its radiated power in some direction. The higher D, the more the antenna can direct its radiated far-fields to some receiver. " - Major lobe of antenna
