Download Millimeter-Wave Quasi-Optical MEMS Steered MMIC Amplifier Array Book in PDF, ePub and Kindle
The development of a 44 GHz MEMS-steered solid-state amplifier array with 100 active elements has been studied. The array has a layered geometry with 10 layers of microstrip circuitry, each containing 10 amplifier/MEMS phase shifter elements configured in parallel as a power combining microstrip/parallel plate waveguide combiner. The final strategy for the grating array and layer array amplifiers was implemented and tested. This involved the construction of a compact array amplifier with a beam launcher consisting of an h-plane sectoral horn with an anti-reflection lens. For loss and reflection optimization, several step geometries were studied for the transition to parallel plate. A split transition scheme was introduced for the transition between parallel plate and microstrip. The MEMS phase shifter fabrication process was studied in more detail to expand the total phase shifting range. Severe reliability issues were encountered, especially in terms of DC isolation of the top metal layer. Different techniques have been used to alleviate this problem, which included using different release methods and the use of a wet metal etch. Additionally, a new process for obtaining more compliant MEMS springs without affecting transmission line parameters was successfully developed, therefore allowing actuation of our phase shifters at lower operating voltages.

Download Millimeter-Wave Antennas: Configurations and Applications Book in PDF, ePub and Kindle
This book comprehensively reviews the state of the art in millimeter-wave antennas, traces important recent developments and provides information on a wide range of antenna configurations and applications. While fundamental theoretical aspects are discussed whenever necessary, the book primarily focuses on design principles and concepts, manufacture, measurement techniques, and practical results. Each of the various antenna types scalable to millimeter-wave dimensions is considered individually, with coverage of leaky-wave and surface-wave antennas, printed antennas, integrated antennas, and reflector and lens systems. The final two chapters address the subject from a systems perspective, providing an overview of supporting circuitry and examining in detail diverse millimeter-wave applications, including high-speed wireless communications, radio astronomy, and radar. The vast amount of information now available on millimeter-wave systems can be daunting for researchers and designers entering the field. This book offers readers essential guidance, helping them to gain a thorough understanding based on the most recent research findings and serving as a sound basis for informed decision-making.

Download Aperture Antennas for Millimeter and Sub-Millimeter Wave Applications Book in PDF, ePub and Kindle
This book presents the technology of millimetre waves and Terahertz (THz) antennas. It highlights the importance of moderate and high-gain aperture antennas as key devices for establishing point-to-point and point-to-multipoint radio links for far-field and near-field applications, such as high data-rate communications, intelligent transport, security imaging, exploration and surveillance systems. The book provides a comprehensive overview of the key antenna technologies developed for the mm wave and THz domains, including established ones – such as integrated lens antennas, advanced 2D and 3D horn antennas, transmit and reflect arrays, and Fabry-Perot antennas – as well as emerging metasurface antennas for near-field and far-field applications. It describes the pros and cons of each antenna technology in comparison with other available solutions, a discussion supplemented by practical examples illustrating the step-by-step implementation procedures for each antenna type. The measurement techniques available at these frequency ranges are also presented to close the loop of the antenna development cycle. In closing, the book outlines future trends in various antenna technologies, paving the way for further developments. Presenting content originating from the five-year ESF research networking program ‘Newfocus’ and co-authored by the most active and highly cited research groups in the domain of mm- and sub-mm-wave antenna technologies, the book offers a valuable guide for researchers and engineers in both industry and academia.
