Integrated Transition with Dielectric Rod for Vacuum Chamber

Gray, D., Le Kernec, J. and Kontis, K. (2023) Integrated Transition with Dielectric Rod for Vacuum Chamber. In: IEICE Technical Committee on Antennas and Propagation (AP), Hiroshima, Japan, 19-20 Jan 2023, pp. 12-17.

Abstract

Conducting monostatic and bistatic radar and propagation measurements across 33 to 75GHz within a vacuum chamber under Mars atmospheric pressure or Moon vacuum while a thruster erodes regolith and rock simulant present a number of difficulties. Passing through the boron glass windows incurred 3dB loss showing the need for a proper low loss mm-wave transition. Such a transition from an external air filled waveguide to an antenna inside the chamber must hold the 101.3kPa to 535Pa or 0Pa pressure difference. A single-piece cross-linked polystyrene filled rectangular waveguide transition to a dielectric rod looks promising to deliver 18 to 21dBi Gain across an octave.
