Which antenna type is best for covering a long corridor in a building?

Omni-directional antennas radiate in 360 degrees horizontally, wasting signal energy through walls and into adjacent rooms rather than channeling coverage down the corridor.

A patch antenna radiates RF energy in a focused, semi-directional beam pattern well-suited for corridor environments. Unlike omni-directional antennas, it concentrates signal down the length of the corridor rather than wasting energy through adjacent walls, providing consistent and efficient coverage along the entire corridor span.

Yagi antennas are highly directional with a very narrow beamwidth typically used for long-range outdoor point-to-point links, not the moderate-range focused indoor coverage a corridor requires.

Dipole antennas are omni-directional in the horizontal plane, radiating signal equally in all directions, which is inefficient for directing coverage along a narrow corridor.
