Coffee Can Radar - Wilkinson Power Divider

June 16, 2006

The original plan of using a surface mount toroidal splitter was dashed when the one unit obtained was defective. Rather than deal with another wait to get another, and for the challenge, we decided to construct a Wilkinson power divider.

We first used a set of approximation functions from Bahl’s A Designer’s Guide to Microstrip Line, in Microwaves, May 1977. They worked fine for the initial microstrip design, but for a confidence check we ran another set of piece-wise approximations obtained from Gupta’s Microstrip Lines and Slotlines.
