Etched ring absorbing waveguide filter based on a slotted waveguide antenna response

Stander, Tinus ; Meyer, Petrie (2008-04)


A cascade of resistively loaded etched rings in waveguide is proposed to act as the load in a balanced FMCW Reflected Power Canceller topology using a slotted waveguide array antenna. A synthesis technique using derived equivalent circuit models, is presented and tested.
