Lens antennaswhy and how they should be used more often in modern communications systemsThis remarkable work provides RF/microwave engineers with complete guidance on how to develop lens antennas, focusing on recent advances in communications engineering where this often overlooked technology is especially useful. It clearly demonstrates the benefits of using lens antennas in modern communication systems, featuring numerous examples, measurement data, fabrication techniques, and real-world applications.Modern Lens Antennas for Communications Engineering explores many types of lens antennas in great detail, from polyrods and low sidelobe antennas to the spherical lens and hemispherical lens-reflector scanning antennas. In addition to design principles and computational techniques, readers will find a host of helpful tips on how to fabricate lens antennas in small batches for assessment, choose the right dielectric material, configure measurement campaigns, and tackle practical issues when constructing antennas and measuring their properties.The book provides information on:
Economically coupling a millimeter-wave circuit into a radiating beam whose polarization and shape is tightly controlled
Utilizing costly spectrum in cellular networks beamed to the ground from platforms high in the upper atmosphere
Tracking two different satellites from a single terminal on a high-speed trainModern Lens Antennas for Communications Engineering is an excellent resource for RF/microwave engineers, designers, and researchers in academia and industry, and anyone wishing to learn how to take full advantage of lens antennas and their many useful and interesting properties.
