Millimeter wave application technology

Condensing millimeter-wave hardware technology into a single volume from a practical perspective.

This book explains the overview of technologies and development trends regarding antennas and high-frequency circuits, which are important component parts. It summarizes the development trends of automotive millimeter-wave radar and millimeter-wave communication as representative applications of millimeter-wave technology, and also introduces millimeter-wave imaging, which is a future sensing technology. Furthermore, to reduce the cost of millimeter-wave systems, high-frequency substrates are used for antennas and high-frequency circuits, as they are crucial technologies that influence the performance and cost of millimeter-wave systems. Examples of high-frequency substrate development are also presented. High-frequency substrates are being developed by various companies, and advancements in performance are being pursued with keywords such as low loss, low cost, multilayering, and stable characteristics, making it a field to watch in the future. Additionally, to maintain stable system performance, it is necessary to avoid interference issues that constantly arise in radio wave systems, and the design of radio wave absorbers specific to the millimeter-wave frequency band is discussed. In the millimeter-wave band, the properties of these materials differ from those at low frequencies, making accurate information on the electrical constants of materials extremely important for the design of antennas and high-frequency circuits. Finally, the book discusses the measurement techniques for the electrical constants of materials, antennas, and radar systems in the millimeter-wave band.
