Nowadays, it is hard to imagine daily life without connecting to cellular communications or wireless local area networks. People are not just accessing digital information in real time but also watching movies and enjoying multimedia data streaming services even in vehicles traveling at high speeds. Technically, contemporary wireless communications systems rely primarily on massive signal processing

As an electrical engineer, I like to view everything, large or small, in terms of an equivalent circuit of resistors, capacitors, inductors, and other components. To help me understand cell biology, I attempted to put together a simple equivalent circuit for a cell and validate it by electrical measurements. I soon found sympathy with far-sighted physical scientists and engineers from a century ago

Semiconductor technology plays an important role in realizing the 5G mobile communication system. One of the technical objectives for 5G is to significantly boost cellular network throughput-by 100 times compared with 4G (to achieve a peak data rate of > 10 Gb/s) [1]. Achieving this goal will require massive multiple input/multiple output (MIMO) antenna technology [2], [3].

As an important part of wireless communication systems, the technology of RF devices and circuits has been progressing rapidly. For high-frequency and high-power applications, vacuum electronic devices (e.g., traveling wave tubes) have been widely used, although the vacuum tube is large in size and hard to integrate.

Lately, R&D of microwave vacuum electron devices (MVEDs) has played a very important role in the technologies of broadcasting, communication, radar, remote imaging, electronic countermeasures, materials research, deep space exploration, and wave spectroscopy. In the 1970s, this widespread role could not have been predicted, as the development of vacuum electron devices faced a serious challenge from

With the rapid development of modern communication and radar technology, there is a need for the miniaturization, planarization, and modularization of microwave and millimeter-wave (mm-wave) systems, without losing excellent performance and reliability. The transmission line is the most basic component of microwave and mm-wave circuits and systems, and its characteristics-including loss, size, integration

In recent years, RF identification (RFID) technology in the ultrahigh-frequency (UHF) range has become increasingly important in many applications, especially in the context of both the Internet of Things (IoT) and Industry 4.0. RFID is no longer simply a matter of identification; today, it is mainly concerned with recording data from the surrounding environment. As a result, researchers are working

Radio-frequency identification (RFID) readers are the main bottleneck when building an RFID system. The cost of the readers can be high, and these devices can be bulky. Moreover, when these RFID readers have to be included in a small mobile device, the cost increases, or the system becomes more complex to put together.

In this article, we discuss how one can make, with modern and low-cost tools, a software-defined ultra high-frequency (UHF) RF identification (RFID) reader. Since we have chosen to leave the discussion of the top-level reader implementation until the very end, an introductory outline is warranted to help guide our audience. We first provide the uninitiated with some background context by answering

In our age of global networks and the Internet of Things, communication and identification with a transponder tagged on goods and products have become increasingly important [1]. There is not only a need for the identification of the labeled objects but also for finding their exact positions in 3D space. Radio-frequency identification (RFID) offers both and is, in fact, already used in a vast field

With the rapid development of newgeneration communication technology such as multiple-input/multiple-output technology, ultrawideband communication, and 5G technology, communication systems have higher requirements for the quality of signal transmissions. Achieving this quality requires attention not only to signal amplitude characteristics but also to phase characteristics because of the long delays

Waveguide components have been widely explored for several decades, due to their inherent merits of low insertion losses, high quality (Q) factors, and a significant power-handling capacity. Historically, cavity-based narrowband filters and multiplexers have been explored and designed for base stations and satellite applications. Compared with using single-mode resonators (SMRs), the implementation

Signal crosstalk and common-mode noise are two issues for engineers when designing today's increasingly complicated microwave integrated circuits [1]. Compared with singleended circuits, balanced circuits can provide high immunity to environmental noise and broadband common-mode rejection capability [2]. Over the past few years, various balanced passive circuits, such as filters [3], antennas [4],

Presented here is an intuitive method for synthesizing the binomial multisection quarter-wave transformer. I discovered this method while teaching an undergraduate course in microwave engineering and termed it the Z-method. I have found that, compared to the approximate method based on the theory of small reflections [1], the Z-method is easier for students to grasp. The technique employs successive

This book looks at ways in which CMOS is pushing the frequency boundary. After an introductory chapter, the book splits into three parts: eight chapters on systems, four chapters on components, and a final chapter on fin field-effect transistors (FinFETs) and process technology. It is a fascinating tour of applications, critical components, and technology. The book has 14 chapters and almost 30 different

Reports on how the COVID-19 pandemic has and will continue to change the business market. To say that the way we work has changed forever should not be controversial. Since I started working as an engineer more than 40 years ago, the way we work has changed dramatically. There are some long-running trends, such as ever-increasing automation, that continue to impact the way we work. There have also

Examines what the author contends are the "cultural differences" most frequently noted between digital and RF electronics. I have recently encountered another cultural conflict in the technological zone of optical communications— more specifically, the process of “detecting” an optical signal to obtain a microwave output. This is a world where the “RF” is light, and “intermediate frequency” (IF) is

Resonances and reactive effects due to higher-order modes represent a rather popular concern among microwave engineers dealing with the design and modeling of passive components. The terms spurious and parasitic are indeed the words of choice when referring to those effects, and, although such a historic bad reputation is well deserved for most applications, in the last decade or so, there has been

Wireless power transfer (WPT) technology gained wide recognition over a decade ago following a resonance coupling WPT study conducted by a group at the Massachusetts Institute of Technology (MIT) [1]. WPT was originally proposed by Nicola Tesla at the end of the 19th century [2] based on a study of near-field inductive-coupling WPT and far-field WPT via radio waves. The first patent involving inductive

Quantum computing could potentially offer faster solutions for some of today's classically intractable problems using quantum processors as computational support for quantum algorithms [1]. Quantum processors, in the most frequent embodiment, comprise an array of quantum bits (qubits), the fundamental computational unit of a quantum computer. Unlike conventional bits, qubits can take a coherent state

The market value for the plastics manufacturing industry is projected to exceed US$700 billion in the coming decade [1].

RF/microwave bandpass filters (BPFs) are fundamental components in high-frequency RF transceivers. On the transmitter side, they limit the transmitted RF signal bandwidth by suppressing out-of-band spurious signals and intermodulation products, which are primarily generated by the nonlinear active stages and can affect other RF systems. On the other hand, in the receiver, they reject out-of-band interfering/jamming
