Abstract: A directional beam switching antenna capable of transmitting/receiving in six directions with 60 degree beam width in six steps. The antenna advantageously uses frequency selective surfaces to block radiation of electromagnetic (EM) waves in unwanted directions and promote transmission of the EM waves in one or more selected directions. The frequency selective surface is made of a single layer of repeated metallic strips and active elements. In the preferred embodiment, only fifteen active elements are used in each of six sections of the antenna, thereby providing a simple, low cost design. The frequency selective surfaces have a high reflection co-efficient when the active elements are in their On state, and a high transmission co-efficient when the elements are in their Off state. Directional transmission is achieved by controlling the state of the active elements.
