Which antenna type provides a 360-degree radiation pattern?

An omnidirectional antenna radiates radio frequency (RF) signals equally in all horizontal directions, creating a 360-degree coverage pattern. This makes them suitable for general coverage in open areas where devices can be located anywhere around the access point. Yagi antennas are highly directional, focusing RF energy in a narrow beam. Patch antennas are also directional, typically providing a broader but still focused beam than a Yagi. The term "directional" is a broad category that includes Yagi and patch antennas, all of which focus RF energy in a specific direction rather than uniformly in all directions.
