This antenna makes efficient  use of the entire aperture for each beam position to  produce a set of shaped azimuth sector beams.  A fed  element excites a field of parasitic elements which  serves as an artificial dielectric lens.  The  challenges of optimizing large parasitic arrays are  discussed, and a successful method of dealing with  the issues is described in detail.  Beam scanning is  accomplished by switching the feed element and  reactive loading on some of the parasitic elements.  Prototype test results are provided.  This antenna  provides a low-cost, compact alternative to  mechanically-scanned or phased array systems with  comparable gain.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843379373\"\u003e\u003ch3\u003eA Robust Synthesis and Optimization Approach\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843379373","offer_id":39497193979997,"sku":"9783843379373","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/5bbdb28e-0550-47f4-844e-b8f093efcac0.jpg?v=1757654460","url":"https:\/\/shop.autorenwelt.de\/products\/design-of-a-switched-beam-scanning-parasitic-array-von-david-de-schweinitz","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
