Simplified design of an X/Ku-band Vivaldi array for rocket exhaust plume diagnostics

摘要

This paper describes the design and fabrication of an 8-element wideband Vivaldi antenna array with an integrated feed network. This array was created for use in an X/Ku-band measurement system for characterizing dynamic rocket plasma, extending previous measurements of this phenomenon. The array is instrumented to help distinguish plume-induced mechanical changes from electrical ones.
