It provides the basic electromagnetic tools required to design and analyse these novel antennas, with sample calculations where relevant. The book presents a focused introduction and valuable insights into the relevant antenna technology, together with an overview of the main directions in the evolving technology of compact planar arrays. While the book discusses the historical evolution of compact array antennas, its main focus is on summarising the extensive body of literature on compact antennas. With regard to the now ubiquitous slot radiator, it seeks to demonstrate how, despite significant antenna size reductions that at times even seem to defy the laws of physics, desirable radiation pattern properties can be preserved. This is supported by an examination of recent advances in frequency selective surfaces and in metamaterials, which can, if handled correctly, be used to facilitate physics-defying designs. The book offers a valuable source of information for communication systems and antenna design engineers, especially thanks to its overview of trends in compact planar arrays, yet will also be of interest to students and researchers, as it provides a focused introduction and insights into this highly relevant antenna technology. 410 0$aSignals and Communication Technology,$x1860-4862 606 $aWireless communication systems 606 $aMobile communication systems 606 $aOptics 606 $aElectrodynamics 606 $aMicrowaves 606 $aOptical engineering 606 $aMetals 606 $aMagnetism 606 $aMagnetic materials 606 $aWireless and Mobile Communication$3https://scigraph.springernature.com/ontologies/product-market-codes/T24100 606 $aClassical Electrodynamics$3https://scigraph.springernature.com/ontologies/product-market-codes/P21070 606 $aMicrowaves, RF and Optical Engineering$3https://scigraph.springernature.com/ontologies/product-market-codes/T24019 606 $aMetallic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z16000 606 $aMagnetism, Magnetic Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/P25129 615 0$aWireless communication systems. 615 0$aMobile communication systems. 615 0$aOptics. 615 0$aElectrodynamics. 615 0$aMicrowaves. 615 0$aOptical engineering. 615 0$aMetals. 615 0$aMagnetism. 615 0$aMagnetic materials. 615 14$aWireless and Mobile Communication. 615 24$aClassical Electrodynamics. 615 24$aMicrowaves, RF and Optical Engineering. 615 24$aMetallic Materials. 615 24$aMagnetism, Magnetic Materials. 676 $a621.382 700 $aSangster$b Alan J.$4aut$4http://id.loc.gov/vocabulary/relators/aut$00 906 $aBOOK 912 $a9910337657603321 996 $aCompact Slot Array Antennas for Wireless Communications$91921585 997 $aUNINA
