In aerospace vehicles, the phased arrays are often in planar configuration. The radar cross section (RCS) of the vehicle is mainly due to its structure and the antennas mounted over it. There can be situation when the signatures due to antennas dominate over the structural RCS of the platform. This necessitates the study towards the reduction and control of antenna/ array RCS. The planar dipole array is considered as a stacked linear dipole array. A systematic, step-by-step approach is used to determine the RCS pattern including the finite dimensions of dipole antenna elements. The mutual impedance between the dipole elements for planar configuration is determined. The scattering till second-level of couplers in parallel feed network is taken into account. The phase shifters are modelled as delay line. All the couplers in the feed network are assumed to be four port devices. It is shown that the array RCS can be reduced considerably for a low observable platform by an optimization of array design parameters even in the presence of mutual coupling. This book presents a systematic step-by-step analytical formulation for RCS of planar half-wavelength centre-fed dipole arrays through various schematics and illustrations. The analytical description and analysis provided in this book should be useful for students, researchers, and design engineers of phased arrays. 410 0$aSpringerBriefs in Computational Electromagnetics,$x2365-6239 606 $aMicrowaves 606 $aOptical engineering 606 $aMathematical physics 606 $aElectronics 606 $aMicroelectronics 606 $aMicrowaves, RF and Optical Engineering$3https://scigraph.springernature.com/ontologies/product-market-codes/T24019 606 $aTheoretical, Mathematical and Computational Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19005 606 $aElectronics and Microelectronics, Instrumentation$3https://scigraph.springernature.com/ontologies/product-market-codes/T24027 615 0$aMicrowaves. 615 0$aOptical engineering. 615 0$aMathematical physics. 615 0$aElectronics. 615 0$aMicroelectronics. 615 14$aMicrowaves, RF and Optical Engineering. 615 24$aTheoretical, Mathematical and Computational Physics. 615 24$aElectronics and Microelectronics, Instrumentation. 676 $a621.3824 700 $aSingh$b Hema$4aut$4http://id.loc.gov/vocabulary/relators/aut$0721045 702 $aR$b Chandini$4aut$4http://id.loc.gov/vocabulary/relators/aut 702 $aJha$b Rakesh Mohan$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910254191303321 996 $aParallel-Fed Planar Dipole Antenna Arrays for Low-Observable Platforms$92515393 997 $aUNINA
