Multiport Antennas for WLAN

This chapter focusses on multiport antennas, antennas equipped with multiple ports, pushing the boundaries of WLAN performance. It begins by outlining the advantages of using these antennasAntenna, including their ability to create multiple data streams and steer beams toward specific users. The chapter then explores various multiport antennaAntenna designs, including classic configurations and innovative multibeam antennas capable of serving multiple users simultaneously. It then discusses two distinct approaches to achieve gain equalization with multiport antennas, showcasing their potential to overcome signal variations and create uniform coverage. Additionally, the chapter provides valuable design guidelines to consider when developing or selecting multiport antennas for WLAN applications. Finally, it concludes by highlighting their role in creating a more robust, efficient, and user-centric WLAN antennas.
