Review of LTCC Technology for Millimeter Waves and Photonics

Application of GaAs Device Technology to Millimeter-Waves

The firstly commercialized millimeter-wave application was the automotive radar, which appeared nearly 10 years ago, for driving safety support. The market size has been growing year by year and is expected to reach a level of around five million units per year in 2016. With the progress in popularity, the radar has been expected to spread even to general cars, therefore, development of lowcost...

Photonics for Millimeter-Wave and Terahertz Sensing and Measurement

This paper describes recent progress of photonicallyenabled systems for millimeter-wave and terahertz measurement applications. After briefly explaining signal generation schemes as a foundation of photonics-based approach, system configurations for specific applications are discussed. Then, practical demonstrations are presented, which include frequency-domain spectroscopy, phase-sensitive mea...

Review of Antenna Technology for Millimeter Wave Automotive Sensors

Automotive sensors for the detection and discrimination of other vehicles on the road, obstacles, and boundaries use miniature radar systems and are heavily dependent in their performance on the antenna system. In this contribution, the requirements for such antenna systems are reviewed and the various options of antenna technology are discussed. In particular, prominent and presently employed,...

Leveraging Millimeter Waves for Security

The fact that Millimeter Wave (mmWave) communication needs to be directional is usually perceived as a challenge; in this paper we argue that it enables efficient secret key sharing that are unconditionally secure from passive eavesdroppers, by building on packet erasures. We showcase the potential of our approach in two setups: beam sweeping to align receiver/transmitter pairs, and vehicle pla...
