Although Radio Frequency Identification (RFID) technology is being used widely for pallet and box-level tracking in the commercial sector, significant technology gaps remain for tracking dense quantities at the item...
A new wireless transceiver was developed that boosts radio frequencies into 100-gigahertz territory, which is quadruple the speed of the upcoming 5G, or fifth-generation, wireless communications...
An algorithm enables localization of humans and robots in areas where GPS is unavailable. The Army needs to be able to localize agents operating in physically complex, unknown, and infrastructure-poor environments. This capability is critical to help find dismounted soldiers and...
A novel patch antenna technology was developed that provides significant benefits to NASA satellite communication applications, offering a unique wide-band/multi-band operating capability. For other non-space applications, the antenna design also offers broadband capability with high gain for...
Antenna characterization techniques are often expensive and time-consuming. NASA’s Glenn Research Center developed a highly versatile and automated system to perform characterization of single or multiple small circuit antennas, printed on-wafer or on other substrates, by measuring the antenna’s...
The Georgia Tech Research Institute (GTRI) is the nonprofit applied research division of the Georgia Institute of Technology (Georgia Tech) in Atlanta, GA. Founded in 1934 as the Engineering...
A pocket-sized antenna was developed that could enable mobile communication in situations where conventional radios don’t work such as underwater, through the ground, and over very...
Researchers have created a fabric that automatically regulates the amount of heat that passes through, depending on conditions; for example, when conditions are warm and moist — such as those of a...
Researchers have created technology that is 10 times more reliable than current methods of producing unclonable digital fingerprints that can be used to...
Accurately measuring semiconductor properties of materials in small volumes helps engineers determine the range of applications for which these materials may be suitable in the...

There's an entire world our eyes miss, hidden in the ranges of light wavelengths that human eyes can't see. But infrared cameras can pick up this light emitted as...
In this compendium of recent articles from the editors of Aerospace & Defense Technology and Tech Briefs, read about how high-frequency electronics advances are enabling new applications in space communications, aviation, the military and more.
Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...
A current-steering digital-to-analog converter (DAC) was developed that achieves improved switching times (up to 75% faster) in high-speed (gigahertz), high-resolution (8-14...
Dr. Sultana won funding to advance a nanomaterial-based detector platform that can sense environmental parameters from minute concentrations of target gases and vapors, to atmospheric pressure and temperature, and then transmit that data via a wireless antenna — all from the same 3...
Innovators at NASA’s Glenn Research Center have developed a hybrid telescope antenna system — Teletenna — to deliver high-data-rate communication over great distances. Teletenna has...
Small unmanned aircraft systems (UAS), also known as micro air vehicles, are promising tools for a variety of military and commercial applications. Some small UAS have flexible wings and are lightweight, making them back-packable and easy to deploy. Most UAS that are...
Lightweighting design is an extensively explored and utilized concept in many industries, especially in aerospace applications, and is associated with the green aviation concept. The...
