Military Radio Antenna Eliminates Electrocution Danger

 

A new radio antenna could help strengthen ease of communication between military troops while preventing electrocution deaths. Developed by California-based United Analytics Corp., the new “body worn” antenna is a small, flexible panel that can fit onto a backpack or be worn underneath clothing or body armor and is designed to replace the larger antennas currently used by … [Read more...]

Microwave Oven Powers Small Devices with Electromagnetic Energy

 

Scientists in Japan have discovered a way to run kitchen appliances using electromagnetic energy scavenged from microwave ovens. While the majority of radiation generated by the common kitchen appliance is directed at the food inside the device, a portion of the energy can still escape through the gap around the door and through the metal-meshed window. So, for consumer … [Read more...]

Signal Analyzers Now Feature Improved Phase-Noise Performance, Sweep Speed

 

Agilent Technologies Inc. has announced several enhancements to two of its X-Series signal analyzers, the midrange MXA and general-purpose EXA, including improvements to phase noise. According to the company, the new improvements will help accelerate searches for spurious signals in the testing of transmitters, active antenna arrays and power amplifiers, and allow engineers to … [Read more...]

RF Antenna Incorporates Shielded Room as Reverberating Antenna

 

AR RF/Microwave Instrumentation, a developer of broadband high power, solid state RF amplifiers and microwave amplifiers, has announced the “Cavitenna” RF antenna, a top-loaded monopole antenna that “[utilizes] the shielded room as a reverberating antenna, and the wall as the antenna's ground plane. As a result, it accommodates extremely high power and corresponding field … [Read more...]

ESA Antenna Test Range Receives Equipment Upgrade

 

The European Space Agency (ESA) has announced the installation of a state-of-the-art Near-Field Scanner (NFS) in the agency’s Compact Payload Test Range at the European Space Research and Technology Centre in Noordwijk, the Netherlands. The new installation will reportedly allow ESA researchers to more thoroughly examine the electromagnetic fields closely surrounding a test … [Read more...]

Giant Radio Telescope Prevents Use of Wi-Fi, Digital Textbooks, Online Standardized Testing at Nearby Public School

 

Students at a small public school in West Virginia are unable to use Wi-Fi because it could interfere with a giant radio telescope located nearby—a restriction that could spell trouble when the state completes its move to an online-only standardized aptitude test within the next two years. Located within the U.S. National Radio Quiet Zone and protected by the Appalachian … [Read more...]

Acoustic Time Delay Device Could Reduce Size, Cost and Complexity of Current Phased Array Systems

 

Researchers from the Georgia Institute of Technology in Atlanta, Ga. have developed a new device that could help reduce the size, cost, complexity and power requirements of current phased array technology. Modern radar systems are depending increasingly on phased-array antennas—a design in which signal beams are directed electronically by grids of solid state … [Read more...]

Double-Ridged Horn Antenna for Radiated Emissions and Immunity Applications

 

Teseq Inc., a developer of instrumentation and systems for EMC emission and immunity testing, has released the PMM DR-01 double-ridged horn antenna for radiated emissions and immunity applications. The corrosion-resistant PMM DR-01 antenna measures approximately 2.2 in x 1.7 in x 5.4 in and features individual calibration and a nominal impedance range of 50 ohms. According to … [Read more...]

Interference Mitigation System for Antenna Remoting Applications

 

Pharad, a developer of small antenna and microwave photonic technologies, has announced the debut of an all-optical interference mitigation system at the 2013 OFC/NFOEC Exposition in Anaheim, Calif., in mid-March. According the company, the new interference mitigation system is the “first all-optical interference mitigation system that can be directly integrated with a fiber … [Read more...]
