As a practicing Antenna engineer for some 14 years, this page
probably comes under the heading “old habits die hard”. The contents
are basically things that I have found interesting or useful over
the years or that I am still tinkering with: Previous work; Test
antennas; How to make a reference dipole (designs are best suited
for the frequency range 800-3000 MHz); A few projects I have worked
on; Planar Scanning (a practical look at the surface currents and
voltages on some common antennas); Balanced measurements (calculating
balanced impedances from single ended S-parameter measurements);
Defining, evaluating and using coordinate transform matrices; VNA
for WinSpice3
