Antenna Engineering Handbook

Why You Should Own a Copy of The Antenna Engineering Handbook

The Harrington Antenna Engineering Handbook is the reference most people in our field keep on their shelf. It's not a textbook. It's a compilation of detailed chapters written by specialists, covering everything from basic wire antennas to reflectors, arrays, and measurement techniques. The 4th edition came out in 2001, and the 5th edition expanded the coverage significantly. It's dense, at times dry, and absolutely worth it when you're stuck on a design problem. I don't recommend reading it cover to cover. That's not what it's for. You pull it out when you need to understand why a particular antenna geometry behaves the way it does, or when you're trying to interpret measured data and need the underlying theory. The individual chapters are generally self-contained enough to let you jump into the section that matters for your current problem.

Understanding the Antenna Engineering Handbook

The core value of this book is breadth. Richard Harrington assembled contributors who were actively working in each subfield at the time. What you get is authoritative treatment of classical antenna theory alongside practical design guidance. The chapters on array synthesis, for example, walk through the mathematics of pattern multiplication, feed network design, and tolerance analysis. The section on reflector antennas covers everything from prime focus to offset configurations, including surface error analysis and spillover calculations. There's a good amount on measurement techniques too — anechoic chamber setup, near-field to far-field transformation, and the practical headaches of outdoor range calibration. If you've ever struggled with getting clean measurements at a test facility, those chapters will save you time.

How to Use It When You're Actually Working on Something

Here's a concrete example. A few years back I was working on a microstrip patch array for a commercial product. We needed tight tolerance on the element spacing because mutual coupling was pushing the pattern off spec. The textbook formulas I had been relying on assumed isolated elements. I went to the Harrington handbook, found the chapter on array analysis, and pulled the mutual impedance formulation for rectangular patches. It gave me the coupling coefficients I needed to adjust the physical layout before committing to the PCB. Without that reference, I would have spent weeks tweaking the design iteratively with a simulator. The trick is knowing where to look. The table of contents is detailed enough to be useful. Skim it first, then read the relevant chapter. Don't bother trying to absorb everything in one sitting.

What the Handbook Gets Wrong or Misses Entirely

The biggest limitation is age. The 4th edition is from 2001. The 5th edition, while broader, still predates the current simulation landscape. If you're doing full-wave electromagnetic design with tools like CST or HFSS, you'll find the computational electromagnetics coverage thin. The book treats method of moments and finite element methods, but it doesn't walk you through setting up a modern simulation or interpreting the results in the context of these tools. Metamaterial antennas and metasurfaces aren't covered at all. That's a significant gap if you're working in RF research or cutting-edge communication systems. The chapters on printed antennas are solid but they assume you're dealing with conventional dielectric substrates. If you're designing something with anisotropic or frequency-selective surfaces, you're on your own. The writing style varies by chapter. Some contributors write clearly and concisely. Others seem to have treated the chapter as an opportunity to present every derivation they've ever worked out. The antenna modeling chapter is particularly heavy on mathematics. If you're looking for a quick practical answer, you might find yourself flipping pages.

Alternatives and When to Use Them

If you need a more balanced textbook that covers both theory and modern computational methods, Balanis's Antenna Theory: Analysis and Design is the standard replacement. It's better organized for learning, has more worked examples, and covers techniques like the finite-difference time-domain method that Harrington barely touches. But Balanis is a textbook. You learn from it. You don't reference it at 11 PM when a client is calling and you need an answer about gain calculations for a parabolic dish. For purely practical design work, consider Microstrip Antenna Design Handbook by Garg et al. It's narrower in scope but more actionable for the most common antenna types used in commercial products. The Harrington handbook gives you the foundation. The Garg book gives you the numbers you can plug into a spreadsheet.

Where to Find It

The Harrington handbook is available through most technical publishers. Check the IEEE Press catalog or Amazon. The 4th edition is older but widely available used. The 5th edition is priced higher but includes substantially more material. If you're doing this for a living, buy the 5th edition. The difference in coverage is worth the extra cost. Libraries at universities with electrical engineering programs usually carry it. If you're a student or you don't want to spend the money upfront, check there first. The book is heavy enough that carrying it around isn't practical, but having it available for deep reference work is something most professionals need at some point. I've owned multiple editions and reference copies at every place I've worked. It's not the most exciting book on the shelf, and some sections haven't aged well, but when you need authoritative treatment of an antenna topic that isn't covered in your favorite simulator's documentation, it's the first place I reach for.
