DOUBLE-LAYER DIRECTOR AND MULTI-FREQUENCY BASE STATION ANTENNA ARRAY

A double-layered director includes a first director and a second director installed above the first director, and the second director includes a dielectric substrate and a split copper foil installed on the dielectric substrate. The present invention arranges a split copper foil on the dielectric substrate. This not only weakens the influence of the resonant current of the director on the high-frequency radiation unit itself, but also simplifies the boundary of the radiation unit, and reduces the coupling and mutual interference between the high-frequency and low-frequency radiation units, and avoids the superposition of scattered waves.
