Design of Phased-Array Antennas for MIMO & Beam-Steering Applications


This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems. It examines the new capabilities recently added to the NI AWR Design Environment platform for developing the RF front-end hardware supporting these new antenna systems, which must be optimized for performance, reliability, compactness, and cost.

Issues In Designing 5G Beamforming Antennas


As 5G networking inches closer to reality, one of the more stubborn problems also will be one of the smallest. Several issues have yet to be cracked with beamforming and massive MIMO antennas, which will make millimeter wave (mmWave) spectrum—a key ingredient in 5G networks—work on multiple devices and base-station locations. Millimeter wave is problematic yet promising. Between bands 30... » read more

Power/Performance Bits: Oct. 9


Spray-on antenna Engineers at Drexel University developed a sprayable form of the 2D material MXene that can be used to create antennas on nearly any surface. The antennas perform as well or better than the ones currently used in mobile devices and RFID tags. The MXene titanium carbide can be dissolved in water to create an ink or paint. The exceptional conductivity of the material enables ... » read more

Power/Performance Bits: July 10


Heating up EV batteries Researchers from Pennsylvania State University developed a self-heating battery that can charge rapidly in cold conditions, a step they hope could spread adoption of electric vehicles. "Electric vehicles are popular on the west coast because the weather is conducive," said Xiao-Guang Yang, assistant research professor in mechanical engineering, Penn State. "Once you ... » read more

Tech Talk: 5G Everywhere


Sarah Yost, senior product marketing manager at National Instruments, talks about the promise of 5G, where it works and where it doesn’t work, and why it’s so critical for so many different markets. https://youtu.be/CzxdrrhSvGY » read more

System-Level Simulation Of Technologies Supporting Enhanced Spectral Efficiency For 5G New Radio


By Gent Paparisto, Joel Kirshman, and David Vye 5G New Radio (5G NR) is the wireless standard defining the next generation of mobile networks. 5G will offer higher capacity than current 4G, enabling a higher density of mobile broadband users and supporting device-to-device and massive-machine communications. 5G research and development will support lower latency, improved reliability, and... » read more

Antenna Design Grows Up


Apple’s iPhone 4 antenna issue represents a classic example of what can go wrong in modern antenna design. Put one in the wrong place, and a seemingly insignificant part can turn a cool new product into a public relations nightmare. Ever since antennas dropped out of sight, most consumers don't give them a second thought. In the 1960s, almost every home had a rooftop antenna. Fast forward ... » read more

Power/Performance Bits: July 26


Flexible MRAM Researchers from the National University of Singapore, Yonsei University, Ghent University and Singapore's Institute of Materials Research and Engineering embedded a magnetic memory chip on a plastic material, flexible enough to be bent into a tube. The new device operates on magnetoresistive random access memory (MRAM), which uses a magnesium oxide (MgO)-based magnetic tunn... » read more

Interference In The Car


Once again, a paradigm shift is upon us. Mobile connectivity has radically changed the automobile’s place in the world of connected everything. And that paradigm will shift even further once the IoE is in full bloom. As all of this unfolds and technology marches on, some see the connectivity of the automobile as being a better and more powerful alternative to the smartphone. It is touted a... » read more

Tackling RF Desense Challenges At The Source


Just imagine you are stepping out of the electronics store with your brand new smart phone. You eagerly scroll down your contacts to dial your best friend and proudly tell them the great news, but as soon as they pick up, your reception is gone! What happened? This problem is commonly described as desense, a degradation of the sensitivity of the receiver due to external noise sources. Desens... » read more
