So in the first case I expect the main lobe on the z-axis, while in the second along the x-axis. Webb2. Pyramidal horn antenna This chapter starts with a short explanation of the two different types of horn antennas. Pyramidal and sectoral horn antennas. Pyramidal horns are flared in two directions, while sectoral horns are just flared in one direction. The planes of the second direction of the sectoral horn are parallel to each other.
