One of my favorite antenna books is available on eBay for another week or so, at the very reasonable price of $65. Optimisation of Wire Antennas by Landstorfer and Sacher does a beautiful job showing how energy flow streamlines aid not only in understanding how antennas work, but also as […]

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 […]
Near-field wireless technology is an emerging area of great importance in Radio Frequency Identification (RFID). Specific applications include low frequency (LF) and high frequency (HF) RFID, Near-Field Communications (NFC), Near-Field Electromagnetic Ranging (NFER), and wireless power transfer. This talk discusses the origins of near-field wireless, surveys applications, presents near-field links […]
Who needs cell phone towers? The largest communications antenna ever placed into orbit, a 22m (72ft) reflector, was launched from Kazahkstan a couple of weeks ago. It will relay signals for a new 4G-LTE mobile phone and data system for North America run by Lightsquared. (BBC News; RedOrbit)
Yesterday’s post on Peter Massey’s Antenna Engineer’s Guide prompted me to think about about why I love antenna engineering. Massey is correct that antenna engineering does provide interesting and varied work, good pay, and job security. But one could say the same about many other jobs. Here’s a slightly edited […]
