Abstract
This paper introduces an ultrawideband wire-grid polarizer measurement standard for focus beam system cross-polarization calibration. The low-cost design enables polarimetric calibration techniques of precision non-destructive material measurements. Principles from wire-grid polarizers and A-sandwich radomes are combined to develop a highly planar standard. An infinite array simulation is included to predict the co-polarized and cross-polarized transmission from 0.1-100 GHz at incidence angles from 0–60 degrees. The design is physically realizable with a specialized printed circuit board technique allowing for low-cost manufacturing and electrically significant polarizer calibration standards sizes. A prototype 305mm x 305mm design is fabricated and mechanically assessed to determine tolerances. Finally, a time-domain gated response isolation scheme is used to characterize the prototype RF performance from 1–20 GHz. The design introduced in this paper may be extended to achieve wire-grid polarizer measurement standards more than 1m diameter for calibration from very low frequencies all the way through W-band.
