There are two main types of WiFi antennas, Omni Directional and Directional
Omni Directional Antennas provide a 360° donut shaped radiation pattern to provide the widest possible signal coverage in indoor and outdoor
wireless applications. An analogy for the radiation pattern would be how an un-shaded incandescent light bulb illuminates a room. Types of Omni
Directional Antennas include "Rubber Duck" Antennas often found on access points and routers, Omni Antennas found outdoors and Ceiling Antennas
used inside buildings and structures.

Directional antennas, as the name implies, focus the wireless signal in a specific direction resulting in a limited coverage area.
An analogy for the radiation pattern would be how a vehicle head light illuminates the road. Types of Directional Antennas include Yagi, Parabolic Grid,
Patch and Panel Antennas.
