5.4 development of a shaped beam low-sidelobe lens antenna with asymmetric pattern5.5 lens antenna payload model; 5.6 multifeed lens; 5.7 multiple beam spherical lens antennas for hap payload; 6 spherical lens antennas; 6.1 introduction; 6.2 spherical lens overview; 6.3 analytical methods; 6.4 spherical lens materials and fabrication methods; 6.5 revisiting the constant-index lens; 6.6 cross-polarization properties of spherical lenses; 7 hemispherical lens-reflector scanning antennas; 7.1 introduction; 7.2 candidate scanning antenna technologies; 7.3 spherical and hemispherical lens antenna.

7.4 hemispherical lens prototype7.5 evolution of a two-layer stepped-index polymer lens; 7.6 a hemispherical lens-reflector antenna for satellite communications; 7.7 a low-index lens reflector for aircraft communications (contribution by d. gray); about the authors; index.

Summary: The aim of this book is to present the modern design principles and analysis of lens antennas. It gives graduates and RF/Microwave professionals the design insights in order to make full use of lens antennas. Why do we want to write a book in lens antennas? Because this topic has not been thoroughly publicized, its importance is underestimated. As antennas play a key role in communication systems, recent development in wireless communications would indeed benefit from the characteristics of lens antennas: low profile, and low cost etc.
