A university requires coverage in large outdoor courtyards. Which antenna type should be used?

Omnidirectional antennas emit RF energy in a 360-degree horizontal pattern, which is ideal for large open spaces like courtyards where clients approach from any direction. They provide uniform coverage without requiring precise aiming or multiple units to fill angular gaps, simplifying both deployment and ongoing maintenance. This even radiation pattern ensures consistent signal availability for all users within the coverage cell.

Patch antennas are semi-directional and concentrate RF energy in a defined forward arc, making them better suited for targeted or point-to-multipoint coverage rather than broad open-area coverage from a single unit.

Dish antennas are highly directional with very narrow beamwidths designed for long-distance point-to-point bridging links, not local area client coverage.

Sector antennas cover a defined angular sector (typically 60-120 degrees) and would require multiple units to achieve full 360-degree coverage of a courtyard, adding cost and complexity compared to a single omni antenna.
