The present disclosure relates to the technical field of antenna, in particular, to a hybrid network antenna.
In a wireless communication system, antenna is an interface between the transceiver and the external propagation medium. When a signal is transmitted, the antenna converts a high frequency current into an electromagnetic wave. When the signal is received, the antenna converts an electromagnetic wave into a high frequency current. As mobile communication technologies continue to develop rapidly, mobile communication networks are also continuously upgraded, and as a key device for mobile communication networks, the base station antenna's performance and practical functions are also continuously enhanced and improved.
For different areas and/or different user groups, the types of base station antennas applied are not the same. During the construction of the traditional base station, a plurality of separate antennas are arranged, wherein each antenna operates in a corresponding frequency band to meet the needs of different regions and/or different user groups. However, the arrangement of a plurality of separate antennas, on the one hand, is not conducive to antenna integration and miniaturization, and on the other hand, is also not conducive to alleviation of the contradiction between the antenna site resources, which also increases the cost of the base station.
