A Double Layer Cross-Slot Aperture-Fed Millimeter-Wave Antenna Array With Wide Axial Ratio Bandwidth
Abstract: This letter presents a double-layer cross-slot aperture-fed antenna array with wide axial ratio bandwidth for 5G millimeter-wave applications. Each of the antenna elements comprises two ...
Abstract: A flexible bionic skin using fiber Bragg grating (FBG) is proposed in this paper, and a double-layer distributed sensing array unit is designed which can realize the detection of pressure, ...
Pratt & Whitney initiated design and development of the R-2800 Double Wasp, America’s first 18-cylinder radial engine, in 1936. With water injection and turbo-supercharging, the R-2800 produced more ...
