Automating Antenna Placement Workflow With PyAEDT


Antenna designs can reach daunting levels of complexity, and nowhere is that truer than in advanced 5G and 6G systems. One of the most difficult problems in this design space is signal degradation stemming from electromagnetic (EM) interaction between the phased array antenna and the host structure itself, such as a base station or satellites. It is a pernicious issue that takes several advance... » read more

Research Bits: March 21


Micropatterning with sugar A scientist at the National Institute of Standards and Technology (NIST) discovered a transfer printing process that can deposit microcircuit patterns on curved and textured surfaces using sugar candy. Transfer printing methods, such as flexible tapes, are often used for surfaces that are difficult to directly print on. But they have difficulty with conforming to ... » read more

The Importance Of Phase-Coherent RF Signal


As the number of higher-throughput applications grows, so does the need for wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication engineers must look for ways to improve spectral efficiency and the signal-to-noise ratio (SNR) of systems. Multiple-input / multiple-output (MIMO) and beamforming can help RF designers achieve diversity, ... » read more

AiP/AiM Design For mmWave Applications — Advanced RF Front-End Design Flows From Concept To Signoff


System requirements for broad bandwidth, millimeter-wave (mmWave) spectrum, phased arrays, and integrated antennas and front-ends are evolving. The challenge for engineers will be achieving the cost, size, and performance requirements that will make these products commercially viable. All these factors align to drive next-generation component integration, which includes embedding the antenna wi... » read more

Overcoming Next-Generation AESA Radar Design Challenges


Phased array antennas were first used in military radar systems to scan the radar beam quickly across the sky to detect planes and missiles. These systems are becoming popular for a variety of applications and new active electronically scanned arrays (AESAs) are being used for radar systems in satellites and unmanned aerial vehicles. As these systems are deployed in new and novel ways, size and... » read more

Power/Performance Bits: Feb. 2


MXene antennas Researchers at Drexel University and Villanova University developed spray-on antennas made of the 2D materials MXene that is flexible and light while maintaining good signal. "This combination of communications performance with extreme thinness, flexibility and durability sets a new standard for antenna technology," said Yury Gogotsi, professor of Materials Science and Engine... » read more

Power/Performance Bits: June 25


Improving IGBTs Researchers at the University of Tokyo developed a power switching device that surpasses previous performance limits, showing that there may still be gains ahead for the silicon-based devices, which have been thought to be approaching their limits. The team's improved insulated gate bipolar transistor (IGBT) used a scaling approach, and simulations showed that downscaling pa... » read more

Gaps In 5G Test


Add one more industry to the long list that analysts expect 5G technology to disrupt—test. While the initial versions of this wireless technology will be little more than a faster version of 4G, concern is growing about exactly how to test the second phase of this technology, which will be based upon millimeter wave. A number of fundamental problems need to be addressed. Among them: T... » read more

MIMO And Phased-Array Antennas For 5G


Evolving communication systems are driving developments in the RF/microwave industry. The large umbrella of 5G focuses on supporting three main technologies: enhanced mobile broadband, which is the natural development of long-term evolution (LTE), massive machine-type communications, also known as the industrial internet of things (IIoT), and ultra-reliable, low-latency communications providing... » read more

The Basics of Amplitude Modulation


Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, it is far more efficient to send data by modulating it onto a higher frequency "carrier wave." Higher frequency waves require smaller antennas, use the available bandwidth more efficiently, and are ... » read more
