RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Antenna Physics: An Introduction (2nd Edition), by Robert ZavrelAntenna Physics: An Introduction (1st Edition), by Robert Zavrel

Antenna Physics: An Introduction, by Robert Zavrel.

Indianapolis, Indiana, April 21, 2021 - Copper Mountain Technologies will be presenting a webinar entitled "Introduction to Antenna Aperture," hosted by none other than Robert Zavrel (W7SX), author of "Antenna Physics: An Introduction" (2nd edition now in print). It begins at 2:00 pm EST on Tuesday, April 27th.

Robert Zavrel (W7SX) - RF CafeRobert is an accomplished RF Engineering Executive with 30 years of applicable experience and a verifiable consistent record delivering technical innovation, streamlined operations, increased productivity, and exceptional leadership and mentoring. The concept of antenna aperture is perhaps the most important antenna specification that is largely ignored by amateur texts. Many commonly published equations for radio engineers and amateurs alike rely upon antenna equations that employ aperture but never explain the fundamentals, they simply give the equations and leave it at that.

The purpose of this brief overview is to explain the concept and relate it to why we should care. Virtually all advanced texts on antenna theory explain aperture in detail since their goal is to provide deep understanding of the subject This is an attempt to provide an empirical fundamental understanding and provide some examples of how critical this antenna characteristic is and offer specific examples as it relates to radio amateur interests.

Introduction to Antenna Aperture: Tuesday, April 27, 2021 at 2 PM EST.
