A software-defined, electronically-reconfigurable antenna technology developed by researchers at the Georgia Institute of Technology has now been tested on land, in the air and on the ocean. U.S. Department of Defense representatives attended an event earlier this year in which the capabilities of Georgia Tech’s Agile Aperture Antenna (A3), which can change beam directions in … [Read more...]
RF Rotary Joints Prevent Cable Entanglement During Antenna Testing
Microwave and RF product supplier Fairview Microwave has released a new line of single channel/single-axis and single-channel/multi-axis RF rotary joints. Fairview’s RF rotary joints are designed to be used wherever RF signals have to be transmitted between stationary and moving parts of a system, including commercial and military radar, land-mobile radio communications and … [Read more...]
Australians to Study Effects of Electromagnetic Environment on F-35
Australian engineers have been contracted by the U.S. government to study the effects of electromagnetic compatibility and interference on the F-35A Joint Strike Fighter (JSF). The Defence Science and Technology Organisation (DSTO) unveiled a full-scale model of the Lockheed Martin-designed aircraft last week that will be used to test the plane's resistance to lightning and … [Read more...]
Valley Current Properties of New Transistor Material Could Outdo Silicon
Researchers at Cornell University have identified and tested a semiconducting compound that could outdo silicon in terms of performance, and could signal the emergence of a new kind of transistor material in electronics. The findings, compiled in the paper, “The Valley Hall Effect in MoS2 Transistors,” published recently in Science, revealed promising conductive capabilities … [Read more...]
RF Conformance Test System for Vehicle-to-Vehicle Applications
Rohde & Schwarz has introduced the new R&S TS-ITS100, the world’s first fully automated test system for standard-compliant testing of RF components for vehicle-to-vehicle communications and intelligent transport systems (ITS) in line with IEEE 802.11p. With its compact size, the RF conformance test system can be used throughout the entire value chain, from R&D to … [Read more...]

Sub-Wavelength Images Could Be Made at Radio Frequencies
Scientists have released new theoretical and experimental work that suggests an innovative method using optical wavelengths to overcome certain restrictions on electric field evaluation. Current methods of mapping electric fields at radio frequencies employ certain metallic structures such as dipoles, probes and reference antennas. These structures, however, must be roughly … [Read more...]
Real-Time Spectrum Analyzer Features 27 MHz IBW and Frequency Sweep of 24 GHz/Sec
Signal Hound has released its new BB60C real-time spectrum analyzer and RF recorder, successor to the Signal Hound BB60A. With significantly enhanced performance compared to its predecessor, the Signal Hound BB60C features a frequency range of 9 kHz to 6 GHz, an instantaneous bandwidth (IBW) of 27 MHz and the ability to sweep the RF spectrum at 24 GHz per second. The BB60C … [Read more...]
