An array of leaky wave antennas for indoor smart wireless access point applications

Abstract

An array of leaky-wave antennas (LWA), designed for indoor smart wireless access points applications is presented in this work. It is designed to produce directive frequency scanning in the 2.45 Wi-Fi band. More particularly, it is demonstrated how three different Wi-Fi channels, namely channel #1 (2.412 GHz), channel #6 (2.437 GHz), and channel #11 (2.462 GHz), can be directed towards different directions in space and offering high gain. In this way, it is proposed a simple channel-hopping technique to provide high signal levels in a wide area, and thus assure high data transmissions. The array is designed in single layer planar technology, using low-cost laminate to provide a low-profile antenna structure which can be mounted on ceilings.
