Malibu-based HRL Laboratories has received funding from the Defense Advanced Research Projects Agency (DARPA) to develop backpack-based antennas transmitting ultra-low frequency (ULF) signals that can penetrate some distance into media like soil, rock, water, and radio-denied environments.
A flexible detector for terahertz frequencies (1000 gigahertz) has been developed by Chalmers researchers using graphene transistors on plastic substrates. It is the first of its kind, and can extend the use of terahertz technology to applications that will require flexible electronics, such as wireless sensor networks and wearable technology. The results are published in the scientific journal Applied Physics Letters.
Fibers made of carbon nanotubes configured as wireless antennas can be as good as copper antennas but 20 times lighter, according to Rice University researchers. The antennas may offer practical advantages for aerospace applications and wearable electronics where weight and flexibility are factors.

5G NR is the technical response to the commercial challenges of eMBB gigabit-per-second bandwidths, ultra-reliable and low-latency communications (uRLLC) for mission-critical applications and massive machine type communications (mMTC). NR is billed as a more capable air interface, and will need to operate in both the frequencies below 6 GHz and above 24 GHz (mmWave) with a frame structure supporting both TDD and FDD, as well as operate in both licensed and unlicensed spectrum.
GaN IC chips are usually delivered to the end user as individual chips stored in plastic chip trays or Gel-Pak.

Guidelines are also provided to aid the user in the assembly of GaN IC die in a manner consistent with desired electrical performance.
Wireless InSite’s Communication System Analyzer provides capabilities for assessing the performance of LTE, WiMAX, 802.11n, and 802.11ac systems. The following example investigates WiFi throughput coverage in a house provided by 802.11ac routers operating at 5 GHz using an 80 MHz bandwidth. The geometry for the house was imported from a CAD file and a flat terrain was placed underneath the house.
Choosing the appropriate amplifier for a system is vital for the system’s total performance. While there are many different characteristics of power amplifiers, this article focuses on an amplifier’s linearity and when it is important to consider in a selection process.
In order for a receiver to properly demodulate an RF signal and recover the data, the signal that arrives at the receiver must be sufficiently higher than the noise. This task can be accomplished with a Low Noise Amplifier (LNA). This article presents the different benefits of using an LNA and how this instrument can improve wireless systems.

FEKO, Altair’s comprehensive electromagnetic simulation software suite, can be used in electronic virtual prototyping and simulation driven designs, including antenna design for many products such as mobile phones, tablets, cameras, laptops, and TVs. The software can eliminate weak antenna designs and reduce the number of prototypes with its proof of concept and comparative studies. Pre-compliance of over-the-air (OTA) radiation performance and specific absorption rate (SAR) can be estimated for the standalone device, or for different usage environments.
