ANTENNAS Understanding Phase Noise from Vibrating Antennas Vibrating antennas distort signals. Previous analyses have focused on how physical distortion of the antenna structure changes beam patterns. The vibrational velocity and acceleration also have an effect, however, producing Doppler distortions that contribute heavily to noise at vibration frequencies up to 1000 Hz. CALL FOR PAPERS Substrate […]
RADAR Miniature mmWave Sensor for High-Accuracy Measurement A highly miniaturized, commercially available millimeter wave radar sensor working in the 121 to 127 GHz range can achieve distance measurements accurate to within ±6 micrometers over a measurement distance of 35 mm. On-chip radar circuitry and external antennas are integrated into an 8 mm x 8 mm, […]
Thermoacoustic Effect Turns Microwaves into Underwater Sound In the thermoacoustic effect, heat from electromagnetic waves striking the water’s surface generates sound waves. A University of Arizona team has demonstrated benchtop thermoacoustic communications (TAC), successfully transforming microwave signals in air into sound signals under water, received by an acoustic sensor. The experiments and theoretical analysis suggest […]
DARPA’s “Diverse Accessible Heterogeneous Integration” Revolution The U.S. Defense Advanced Research Projects Agency’s DAHI (Diverse Accessible Heterogeneous Integration) continues to push the limits in on-chip integration, new materials, and improved silicon and gallium nitride technology to address critical challenges for next-generation microwave and millimeter-wave systems. CALL FOR NOMINATIONS Candidates for MTT-S Leadership The MTT-S Nominations […]
Controversial Satellite-Messaging Startup Higher Ground Cleared for Takeoff In the face of industry opposition, U.S. regulators have okayed a smartphone accessory that uses microwaves to send text messages and email via geostationary satellites. Up to 50,000 Higher Ground SatPaq could be deployed in the U.S., promising cheap, reliable messaging far from cellphone towers. Some telecom […]
MESSAGE FROM PRESIDENT DYLAN WILLIAMS A Future of Inclusion and Engagement Out-going President Ke Wu and I share similar visions for the Society. This common ground has led to a close relationship in which I often found myself working to support Ke’s goals, something that I found extremely rewarding: a commitment to inclusiveness, a policy […]
Message from President Ke Wu Time to Renew, Time to Expand Have you renewed your IEEE/MTT-S membership? If you have, I thank you for your loyalty to MTT-S. If not, you can easily renew on-line. You can also help MTT-S by recruiting friends and colleagues as new members of our Society. We have been working […]
Proof-of-Concept Demonstration of Vector Beam Pattern Measurements of Kinetic Inductance Detectors An international team of researchers from the U.S., the Netherlands, and Japan presents the first vector beam pattern measurement of microwave kinetic inductance detectors (MKIDs). The method should facilitate vector beam pattern measurements using direct detectors, reducing systematic error and allowing near-field as well […]
RFID Perfect Isolation: Coping with Self-Jamming in Passive RFID Systems Passive RF identification readers transmit a continuous-wave signal to remotely power up batteryless transponders. At the same time, they receive a backscattered signal at the same frequency. Strong continuous-wave signals can leak into the receiver, drowning out backscattered signals. Fixing the problem requires high-dynamic-range capability […]
THZ TECHNOLOGY Wireless Transmission at up to 60-Gb/s in the 400-GHz Range Researchers at the Technical University of Denmark, with colleagues from the University of Cambridge and Zhejiang University, moved frontiers of optoelectronic transmission past the 300 GHz range by demonstrating scalable data transmission of Nyquist quadrature phase-shift keying signals at 60 gigabits per second […]
TECHNOLOGY China Launches First Quantum Communications Satellite The first spacecraft designed to perform quantum communications was launched from the China’s Jiuquan Satellite Launch Center on 16 August at 1:40 a.m. local time. The mission, dubbed Quantum Experiments at Space Scale (QUESS), is a milestone for researchers building the technology needed to create unhackable large-scale quantum […]
Full-Duplex Chip Will Create a Wireless Bandwidth Bonanza Today’s radio technology has almost nothing in common with its counterpart from a century ago. Countless advances have produced gear that is fantastically smaller, more reliable, and more efficient in its use of power and bandwidth. And yet, one enormous limitation remains from long ago: Radios still […]
SOCIETY Understanding MTT-S’s Worldwide Member and Geographic Activities Today, MTT-S has some 200 chapters in every part of the world. These may be Single Society, Joint Society, Technical Council, or Student Branch Chapters. The 36-member MTT-S Member and Geographic Activities committee helps form and support these chapters and promotes membership in the Society as a […]
MEETINGS Get Ready for the 2016 International Microwave Symposium IMS2016’s technical program opens Monday, 23 May, in San Francisco with The Birth and Death of the Cell Phone, the plenary address by Dr. Martin Cooper, the Father of the Cell Phone. Following four days of programs, the meeting closes on 26 May with National Instruments […]
