Antennas and Microwaves
Welcome to my Antennas and Microwaves page, I hope you find your visit interesting
and informative. As a practicing Antenna engineer for some 14 years, this page probably
comes under the heading “old habits die hard”. However, the site’s existence may
go some way to proving that life in rural France hasn’t turned me into Banjo playing
hillbilly just yet -
The contents are basically things that I have found interesting or useful over the years or that I am still tinkering with.
Contents
> How to make yourself a reference dipole. Designs are best suited for the frequency
range 800-
> A few of the projects I have worked on.
> A practical look at the surface currents and voltages on some common antennas.
> Calculating balanced impedances from single ended S-
> Defining, evaluating and using coordinate transform matrices.
> Vector Network Analyser script for WinSpice3, including Noise Figure analysis in a Microwave system.
> Useful links
> A scalable design for a circularly polarised Reflect Array . Presented in 3 pages that include NEC model, design spreadsheet, construction details and measured results.
> Low cost prototyping of microwave PCBs using a desktop sign maker.
