Can you clarify the definitions of E-plane and H-plane in antennas again?

While studying radiation patterns, I often encounter E-plane and H-plane terminology.
I want a clear, concise explanation of what these planes represent, how they relate to the electric and magnetic fields, and why they are commonly used in analysis.

From my experience, the E-plane is the plane containing the electric field vector and the direction of maximum radiation, whereas the H-plane contains the magnetic field vector and the same maximum radiation direction. I have seen these definitions used consistently in measurement and simulation because they provide standard views of an antenna’s directional characteristics. I would recommend always analyzing both planes: the E-plane helps assess main lobe width and polarization, while the H-plane shows pattern symmetry and side-lobe structure. Understanding these planes is essential for antenna characterization, verification, and comparison.
