Designing a Narrowband 28-GHz Bandpass Filter for 5G Applications (为5G应用设计窄带28-GHz带通滤波器)

5G represents the next milestone in mobile communications, targeting more traffic, increased capacity, reduced latency, and lower energy consumption than its predecessors. To achieve these goals, networks will need to increase bandwidths through carrier aggregation and a push into millimeter-wave spectrum, all while improving spatial efficiency with base station densification and massive multiple-in-multiple-out (MIMO) and […]
