Microstrip Antenna Design


A significant performance element in communication and radar systems, as well as wireless devices, is the antenna, which may be defined as a transducer between a guided electromagnetic (EM) wave propagating along a transmission line, and an EM wave propagating in an unbounded medium (usually free space) or vice-versa.1 The antenna is required to transmit or receive EM energy with directional an... » read more

Measuring Frequency Dependence Across 5G mmWave Bands (NIST)


New research paper from NIST, "Methodology for Measuring the Frequency Dependence of Multipath Channels Across the Millimeter-Wave Spectrum." Abstract "Millimeter-wave (mmWave) communications promise Gigabit/s data rates thanks to the availability of large swaths of bandwidth between 10–100 GHz. Although cellular operators prefer the lower portions of the spectrum due to popular belief ... » read more

Using Periodic Calibration Of Antennas to Ensure the Ongoing Performance Of OTA Systems


Seen or unseen, antennas are essential to virtually every aspect of our connected world. In any over-the-air application—communication, navigation, radar, and so on—signal quality is heavily dependent on the performance of the transmitting and receiving antennas. In addition, when testing any of today’s electronic devices for electromagnetic interference (EMI) and electromagnetic compatib... » read more

Over-The-Air (OTA) Test Socket And Handler Integration Technology For 5G Mass Production Testing


This paper presents the integration of socket, measurement antenna and handler for over-the-air (OTA) testing of antenna-in-package (AiP) devices using automated test equipment (ATE) for 5G applications. The design and characteristics of sockets for performing OTA testing in the radiating near field are also discussed. The paper also describes the structure of OTA handler integration using thes... » read more

Demand Grows For Reducing PCB Defects


Board manufacturers are boosting their investment in inspection, test and analytics to meet the increasingly stringent demands for reliability in safety-critical sectors like automotive. This represents a significant shift from the past, where concerns about reliability primarily targeted the devices connected to printed circuit boards. But as SoCs become disaggregated into advanced packages... » read more

Power/Performance Bits: April 28


Flat microwave reflector Researchers from Los Alamos National Laboratory developed a new flat reflector for microwaves that could improve communications while providing a better form factor. It also breaks reciprocity, effectively turning it into a one-way mirror. The flat reflector can be reconfigured on the fly electronically, allowing it to be used for beam steering, customized focusing,... » read more

The Growing Challenges Of 5G Reliability


The test field is getting more complicated as chips become larger, more heterogeneous, and subject to almost constant changes. Nowhere is this more evident than in 5G, where standards are still evolving and use cases are still being defined. Without passing test, no technology advances. But those definitions are subject to change, and they can change again over time. The communications in... » read more

GaN Versus Silicon For 5G


The global race to launch 5G mmWave frequencies could provide a long-anticipated market opportunity for gallium nitride (GaN) as an alternative to silicon. GaN is more power-efficient than silicon for 5G RF. In fact, GaN has been the heir apparent to silicon in 5G power amplifiers for years, especially when it comes to mmWave 5G networks. What makes it so attractive is its ability to efficie... » read more
