Antennas & Microwaves Resources
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
