Abstract

The patent of the present invention relates to the technical field of base station antennas, in particular to a double-layer director and a multi-frequency base station antenna array using the same. The double layer director includes a first director and a second director mounted above the first director, the second director including a dielectric substrate and mounted on the dielectric substrate Split type metal copper foil. The invention reduces the influence of the resonant current of the director on the high-frequency radiation unit itself by arranging the split type metal copper foil on the dielectric substrate, and also simplifies the boundary of the radiation unit and reduces the coupling between the high and low frequency radiation units. And mutual interference, avoid the superposition of scattered waves to distort the pattern, so that the multi-frequency base station antenna has a consistent and stable horizontal half-power lobe width and gain in the working frequency band.

Description

technical field [0001] The patent of the present invention relates to the technical field of base station antennas, in particular to a double-layer director and a multi-frequency base station antenna array using the same. Background technique [0002] With the rapid development of the mobile communication industry, people's requirements for mobile networks are gradually increasing, and in the current environment of coexistence of 2G, 3G, 4G and 5G networks and tight tower resources, base station antennas are required to be multi-frequency and miniaturized. Therefore, multi-port broadband base station antennas are increasingly favored by the market. [0003] The multi-port wide-band base station antenna designs more antenna arrays without increasing the antenna width, which will reduce the spacing between the arrays and increase the mutual influence between the arrays. In this case, the operating frequency band is required. It has a consistent and stable radiation pattern in...
