Abstract :
The paper presents the design of an on-axis coupled structure which is planar double-sided and suited for fabrication with deep X-ray lithography. It is a standing wave structure with an operating frequency of 91.392 GHz and is designed for the π-mode. End cells and input power coupler are matched numerically by means of the code GdfidL. The main RF parameters are also determined numerically. Reflection and bead pull measurements with a scaled-up model at 10 GHz are presented
