Millimeter-Wave Antennas for Mobile Devices and Networks

2019 12th Global Symposium on Millimeter Waves (GSMM), 2019
Beam-steerable millimeter-wave antennas may enable more efficient use of RF energy in line-of-sight propagation paths than the currently used antennas at microwave frequencies. This paper discusses the challenges related to millimeter-wave antennas for mobile devices and networks and reviews possible approaches for realizing beam-steerable antennas for

InP Devices For Millimeter-Wave Monolithic Circuits

SPIE Proceedings, 1989
High efficiency, mm-wave operation has been obtained from lateral transferred-electron devices (TEDs) designed with a high resistivity region located near the cathode contact. At 29.9 GHz, a CW power output of 29.1 mW with a conversion efficiency of 6.7% has been achieved with cavity-tuned discrete devices.

Millimeter-Wave Active Solid-State Devices

SPIE Proceedings, 1985
The renewed interest in millimeter-wave systems in recent years has stimulated development effort of various solid-state devices. As a result, millimeter-wave IMPATT and Gunn device technologies are now well established for systems applications and the GaAs FET technology has been progressing rapidly extending its upper frequency range to beyond 70 GHz.

A sub-millimeter wave line imaging device

SPIE Proceedings, 2010
In this paper we present a single mode active device for sub-millimeter wave line imaging. The illuminated scene is imaged through focusing optics onto a device we have developed and have dubbed a spatially selective mask (SSM). This device transmits parts of the image onto a heterodyne receiver.

New devices for millimeter-wave applications

Annales Des Télécommunications, 1997
The possibilities for future developments of mm-wave devices are reviewed. New concepts and extensions of presently available devices are considered concerning sources, amplifiers and mixing. We discussed such ideas as micro-cavity triodes unbedded in the semiconductor chip with first experimental evidence available.

Millimeter-wave CMOS device modeling and simulation

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
Challenges for modeling and simulating active and passive 130 nm CMOS devices at mm-wave frequencies (>30 GHz) are discussed. Small-signal lumped circuits with appropriate parasitic elements are used to model the active transistor devices with excellent broadband accuracy.

Millimeter waves hybrid devices - theory and simulation

Third IEEE International Vacuum Electronics Conference (IEEE Cat. No.02EX524), 2003
Combination of different types of electronic devices in one engineering design is one of ways of the output characteristics improvement and extension of electronic-wave systems capacities. In the present report the O-type millimeter waves amplifier consisting of resonance and non-resonance stages is theoretically considered that allows to combine in ...
