Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book addresses the design and analysis of different reflectarrays and transmitarray antennas to meet these requirements. A reflectarray is made up of an array of radiating elements that provide a preadjusted phasing to form a focused beam when it is illuminated by a feed, in a similar way to a parabolic antenna. Printed reflectarrays combine certain advantages of reflector antennas and phased arrays. The reflectarray antennas design in this work includes five antennas. The second part in this book discus five designs of the transmitarray. The first transmitarray is single layer transmitarray antenna using rectangular dielectric resonator as the unit cell elements. Two different constructions for the unit cell of the transmitarray are used.The transmitarray is a multilayer dielectric resonator antenna transmitarray for fixed RFID reader applications is presented at 5.8 GHz. A circularly polarized 9×9 square DRA transmitarray is designed at 5.8 GHz for far-field RFID applications. A design of 9×9 near-field focused DRA transmitarray for fixed RFID at 5.8 GHz is investigated. The properties of the NF-focused transmitarray are compared with the far field transmitarray designed. 292 pp. Englisch.…
