Noted antenna expert, Alan Boswell, was kind enough to share his thoughts on the second (revised) edition of The Art and Science of UWB Antennas. His review follows… The first thing to say to someone familiar with antennas who picks up this book is that its subject matter is not […]

Alan Boswell Reviews The Art and Science of UWB Antennas




SafeSpot protects workers by warning of potential accidents before they happen.
SafeSpot™ systems make busy workplaces safer by warning pedestrians and forklift drivers of potential collisions. The system triggers a warning around blind corners if a forklift-forklift or forklift-pedestrian collision is imminent. Q-Track’s innovative system employs near-field electromagnetic ranging to detect proximity of forklifts and passive IR to detect pedestrians. Workers […]

UWB Book Slider
Professor Steve Holland of the Milwaukee School of Engineering is an expert on UWB antennas and broadband matching. He reviewed Chapter 4 of my book as I was writing it, and he provided me with helpful feedback and insights on matching UWB antennas. His conference paper “Wideband Impedance Matching Techniques” […]

Another Great Review for The Art and Science of UWB Antennas



Can a preface itself have a preface? At the risk of being hopelessly self-referential, I suppose that’s how one might characterize this post. The preface to the second edition of The Art and Science of UWB Antennas follows. By way of introduction, the preface was actually the last part of […]

Bookplate to be included with every signed copy of The Art and Science of UWB Antennas.
Every signed copy of The Art and Science of UWB Antennas will come with a complimentary bookplate. Designed by Patricia Forrest and inspired by a classic design from 1950s science fiction illustrator Ed Emshwiller, the bookplate features equations and graphics from the text. Design elements include: Impulses combining destructive on […]

ATLOSCon 2015
I’m presenting a talk on “Fields Versus Action-At-A-Distance” at ATLOSCon 2015 in Atlanta this morning. This talk focuses on the conflict between the action-at-a-distance and the field approach to physical understanding from the days of Newton and Descartes to the present. Faraday devised the field concept in reaction to then prevalent […]

Fields Versus Action At A Distance – How Electromagnetics Works



Some distinguished early readers offer enthusiastic reviews for the revised second edition of The Art and Science of Ultrawideband Antennas. “Schantz introduces time domain methods in antenna engineering and microwave techniques, which relate to ultrawideband signals in this expanded second edition. The book is delightfully illuminating, and includes well-researched historical […]

Enthusiastic Reviews for The Art and Science of UWB Antennas


At long last I’m done with my book so I have time to update my blog. I will be making some changes over the next week, so don’t be surprised if you happen across some formatting glitches. Also, I have a few comments pending to which I’ll respond soon.

This week, I’ll be presenting my paper on “A simple procedure for measuring gain of very electrically small antennas” at the 2014 Loughborough Antenna and Propagation Conference. Gain measurements of very electrically small antennas (VESAs) present special challenges. These antennas radiate with poor efficiency, and great care is needed to […]

A Simple Procedure for Measuring Gain of Very Electrically Small Antennas


Today, I am presenting a seminar on some diverse topics for the folks in the Antennas and Electromagnetics Research Group at Queen Mary University, London. Here are links to some slides: Three Centuries of UWB Antennas Near-Field Wireless Technology The Time Domain, Superposition, and How Electromagnetics Really Works A couple […]

Allerton
Last week, I traveled to the Allerton Park and Retreat Center to present a new paper on fundamental electromagnetic physics at the 2014 Antenna Applications Symposium. My paper, “On Energy Flow in Standing Waves,” analyzes and explains the propagation of energy in a variety of standing waves. The conventional point […]

The Heaviside Memorial Project recently completed their restoration of the memorial Heaviside's
The Heaviside Memorial Project successfully raised funds and completed the restoration of the memorial to Oliver Heaviside and his family in the Paignton Cemetary near Torquay, Devon. Details and additional photos of the unveiling ceremony are available at their web site. The group, organized by the Newcastle Electromagnetics Interest Group […]

A Heaviside Update – Memorial Project to Republish Heaviside Biography



Heaviside Grave 2
He developed the theory of transmission lines, coined such terms as inductance, impedance, and admittance, and rewrote James Clerk Maxwell’s awkwardly expressed equations into the vector form familiar to any student of electromagnetics. Today, Oliver Heaviside’s neglected tombstone is barely legible and is beginning to lean. Chris Spargo and Professor […]

Time Domain PulsON Logo
Yesterday, UWB pioneer Time Domain announced their acquisition by a private equity group led by Bonaventure Capital and Fidelis Capital. Time Domain did not disclose the terms of the transaction. Additional details are available in a statement from the company and in coverage from the Huntsville Times.

One benefit of working at Q-Track is the opportunity to collaborate with talented people for whom  radio is a passion, not just a profession. This past weekend, my Q-Track colleague, Mark Brown [N4BCD], participated in the American Radio Relay League (ARRL) “Field Day.” The weekend-long exercise tests the ability of […]

I didn’t have time to address a few additional points in my previous post on creativity and innovation. In this post, I wanted to sumarize the evidence underlying my claim that most of innovation results from industry reworking, improving, and advancing existing technology and not from the direct application of […]
