A directional antenna transmits the signal in a targeted way. First, it directs coverage in a particular area they are mounted.
Fremont, CA: Omni-directional antennas broadcast signals in every direction around it, like poles sending signals on a 360-degree circular plane. Omni-directional antennas are the default choice on most access points.
With Omni-directional antennas, WiFi connections can be created in any direction and alleviate effort in planning wireless communication between remote buildings. An instance of this antenna is a dipole antenna.

Nonetheless, since the signal is sent in all directions, it gets weaker with distance. Also, if all the receiving nodes are in one direction, the other direction's signal transmitted is wasted.
Omni-directional antennas can be used in small and home office WiFi deployment enterprises.
A directional antenna dispatches the signal in a focused way. It directs coverage in a precise area in which they are mounted. They're the default choice for outdoor PTP access point wireless networks.
A directional antenna centers the WiFi signal in a specific direction, thus providing a better gain, unlike Omni-directional antennas. It also mitigates background noise or interference since the antenna cannot hear the WiFi signal from any other direction, excluding the ones received from where it is pointed. It also expands the signal traveling length in a specific direction, making the directional antenna a perfect option for long-distance connections.
But to get the necessary throughput, the connection between the directional antenna should be planned well. Some instances of directional antennas are yagi antenna, parabolic/dish antenna, grid antenna, and sector antenna.
Directional antennas are used for the wireless network over long distances and for outdoor wireless communication.
