High Performance Ceiling Mount Antennas Yields Industry Low Peak Gain

 

A new multiple-input/multiple-output distributed antenna system has been introduced by Pulse Electronics. This DAS ceiling mount system includes high port-to-port isolation and improved gain patterns for both of its ports. "Often MIMO antennas have problems with non-circular gain patterns with high deviation from min-to-max gains. In MIMO or neutral host applications the … [Read more...]

New Antenna Yields Results

 

A new antenna has been designed that uses “ionized gas in fluorescent light tubes to transmit Internet wireless frequency signals throughout a building with the aid of already existing electrical wiring.” This works because the gas turns into plasma when it it’s electrically charged and this means frequency signals can be sent and received since the plasma becomes a conductive … [Read more...]

4G Study Highlights Need for More Thermal Loss Research

 

A new study from Danish researchers suggests the ongoing push towards global 4G roaming and high-quality, frequency-reconfigurable antennas will need to account for new loss capacities not considered by previous technology. The worldwide demand for 4G technology and higher data rates in cell phones has led to a new, urgent need for frequency-reconfigurable or tunable antennas. … [Read more...]

Wireless Charging Approach Could Power Vehicles on the Move

 

A new approach for transmitting power wirelessly to electric automobiles could bring the development of highway stations capable of powering fast-moving vehicles closer to reality. Researchers at North Carolina State University have developed new techniques for transferring power to moving electric vehicles that improves on previous methods. The team designed a series of … [Read more...]

Digital Phase Shifter USB RF Modules for Economical Configurable RF Test Measurements

 

Saelig Company, Inc. is now offering Telemakus’ TEP2000-4and TEP4000-5 digital phase shifters for applications including testing of phased array antennas and other RF equipment. These laboratory-quality phase shifters feature minimum phase range of 360 degrees (400 degrees typical) with 12-bit, 0.25 degree resolution. The TEP2000-4 operates over the bandwidth of 1 to 2 GHz, … [Read more...]

Tunable Nanoantennas Made More Customizable than Ever Before

 

Researchers at the University of Illinois at Urbana-Champaign have developed a new kind of tunable nanoantenna that could point towards novel plasmonic-based optomechanical systems that use plasmonic field enhancement to instantiate mechanical motion. The research, led by Kimani Toussaint, Ph.D., associate professor of mechanical science and engineering at the University of … [Read more...]

Researchers Boost Connectivity of Musical Wi-Fi Gloves

 

Scientists from the University of Bristol and the University of the West of England (UWE Bristol) have improved the performance of a pair of musical Wi-Fi gloves worn by popstar Imogen Heap. Used during Heap’s experimental live music performances to control both music and visuals with a series of gestures, the so-called Mi.Mu glove system must be robust enough to cope with … [Read more...]

Beam-Switching Antenna Compensates for Aircraft Movement

 

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...]

Researchers Make Flat Surface Behave Like Spherical Antenna

 

Researchers from Southeast University in China have created a new artificial surface that can bend and focus electromagnetic waves similar to an antenna. The achievement, which the team is calling “the first broadband transformation optics metasurface lens,” could lead to the creation of new types of antennas that are flat, ultra low-profile or that conform to the shape of … [Read more...]

Software for Installed Antenna Analysis Receives Update

 

Delcross Technologies has announced version 4.0 release of its Savant software for modeling the installed performance of antennas on electrically large vehicles. New features in this release of Savant include multi-bounce edge-diffraction rays that improve accuracy by modeling antenna interactions with shadowed portions of the platform, an integrated workflow with CST STUDIO … [Read more...]
