摘要

Recently, for Radio Frequency (RF) signalidentification on air vehicles, it has become critical to not onlybe able to detect the direction and angle of arrival of signals, butto also properly identify the polarization of such signals. Fordecades, cavity-backed dual-spiral antennas were heavily usedfor this purpose. However, that required the placement of bothright-hand and left-hand elements to perform this function.Due to limited space and other issues, an alternative type ofbroadband antenna had to be identified. The Cavity-BackedDual-Sinuous (CBDS) antenna makes an excellent replacementfor this function. With its elements rotated 45° about its center,each element exhibits slant linear performance. Such anantenna, paired with proper connections and detectionhardware, allows the detector to determine the polarization ofarriving RF signals. A CBDS antenna was developed in theWIPL-D CEM code. Its RHCP and LHCP performance wasstudied over a broad range of frequencies. Results did prove thatCBDS antennas have excellent broadband performance andpolarization extraction.
