The fabrication can be done by hand-cutting simple shapes of foil with a knife or by cutting more complex shapes of foil with a 2D cutter from a hobby store [1]. We provide a brief overview of the theory of operation for the FMCW system and each component used. We then describe the design procedure for each component along with experimental results from the fabricated components. The frequency of operation was chosen to be 925 MHz, or around 1 GHz. This decision was made for multiple reasons. First, the frequency is within an Industry, Science, and Medicine (ISM) band. Second, this enabled easy fabrication of microwave transmission-line circuits (m/4 is roughly 40 mm) and reasonably easy hand-soldering of discrete components for termination and amplifier biasing. Operation at the 2.4-GHz ISM band for non-North American applications is a simple shift of frequency in the design targets, but the theory remains the same.}, number={5}, journal={IEEE MICROWAVE MAGAZINE}, author={Dwye, Matthew and Ricketts, David S.}, year={2020}, month={May}, pages={136–145} }
