Refer to the exhibit. Which type of antenna is shown on the radiation patterns?

A patch antenna typically has a broader, somewhat directional pattern, but not as sharply focused as the one shown.

A dipole antenna usually has a roughly omnidirectional pattern in the horizontal plane (like a donut shape) and nulls off the ends.

An omnidirectional antenna emits RF energy equally in all directions in a horizontal plane, producing a circular or donut-shaped radiation pattern, which is contrary to the highly focused pattern shown.

The radiation pattern shown in the exhibit, characterized by a highly focused main lobe and minimal energy in other directions, is indicative of a directional antenna. A Yagi antenna is a type of directional antenna that provides high gain in a specific direction, making it suitable for point-to-point connections or extending range in a particular sector, which aligns with the pattern's visual representation.
