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 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.
