It includes numerous case studies demonstrating how to design and implement different CP antennas in practical scenarios. This book is of value for researchers; system engineers (antenna, telecom, space and satellite); postgraduates studying the subjects of antenna and propagation, electromagnetics, RF/microwave/millimetre-wave systems, satellite communications and so on; technical managers and professionals in the areas of antennas and propagation. -- |cEdited summary from book. 588 0 Print version record and CIP data provided by publisher. 590 O'Reilly|bO'Reilly Online Learning: Academic/Public Library Edition 650 0 Spiral antennas. 650 0 Transmitting antennas. 650 0 Antenna radiation patterns. 650 0 Polarized beams (Nuclear physics) 650 6 Antennes spirales. 650 6 Antennes d'émission. 650 6 Diagrammes de rayonnement d'une antenne. 650 6 Faisceaux polarisés (Physique nucléaire) 650 7 Antenna radiation patterns|2fast 650 7 Polarized beams (Nuclear physics)|2fast 650 7 Spiral antennas|2fast 650 7 Transmitting antennas|2fast 700 1 Luo, Qi,|d1982- 700 1 Zhu, Fuguo. 776 08 |iPrint version:|aGao, Steven.|tCircularly polarized antennas.|dChichester, West Sussex, United Kingdom : John Wiley & Sons Inc., 2014|z9781118374412|w(DLC) 2013030500 856 40 |uhttps://ezproxy.naperville-lib.org/login?url=https:// learning.oreilly.com/library/view/~/9781118790519/?ar |zAvailalbe on O'Reilly for Public Libraries 938 YBP Library Services|bYANK|n12879567 938 YBP Library Services|bYANK|n11072618 938 YBP Library Services|bYANK|n11323728 938 EBSCOhost|bEBSC|n658943 938 ebrary|bEBRY|nebr10799632 938 Books 24x7|bB247|nbke00063493 938 Askews and Holts Library Services|bASKH|nAH25960827 938 Askews and Holts Library Services|bASKH|nAH25960828 938 IEEE|bIEEE|n6670809 994 92|bJFN
