Abstract: This article presents an X-/Ku-band shared-aperture phased array antenna featuring a low-frequency ratio of 1.2 and achieving over 30 dB of isolation between the X-band (10.7–12.7 GHz) and ...
Abstract: When itcomes to physical layer security (PLS), a combined technique of randomized radiation and frequency diverse sub-arrays (FDSAs) with nonlinear frequency offsets (FOs) can produce a ...
