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 - close friends have their own opinions on this!

 

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 800-3000Mhz but could be scaled outside this band with a little experimentation.

> 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-parameter measurements.

> 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.
