Antenna Types
Wireless LAN antennas are available in a variety of styles, shapes, and radiation patterns. In addition, antennas are normally rated for indoor or outdoor use, depending on weather resistance and mounting options. Antennas are usually designed for a specific frequency range and are approved by the local regulatory body, such as the FCC in the US. There are two basic types of antennas, omnidirectional and directional, which are discussed in the following sections.
