Abstract: This application provides an antenna module and a base station system. The antenna module may transmit an electromagnetic wave of a specific frequency band. The base station system includes: a signal tower, a first antenna module, and a second antenna module. The first antenna module and the second antenna module are separately fixed at the signal tower, and share a same antenna installation platform on the signal tower; a distance between a center point of the first antenna module and the signal tower is less than a distance between a center point of the second antenna module and the signal tower. The solutions in this application can enable the base station system to implement multi-band coverage. The antenna module in the system can operate independently without affecting each other, and can be mounted and disassembled separately.

Abstract: An antenna and an antenna system that has the antenna, and relates to the field of wireless communication technologies. The antenna can allow a high frequency to pass through and block a low frequency or allow the low frequency to pass through and block the high frequency, and can be used in combination with other antennas to form an antenna system. In addition, in the antenna system, the antenna can also share a same antenna aperture surface with other antennas. The antenna can reduce costs while meeting a working requirement of a multi-band antenna, and can be used for flexible and changeable usage scenarios.
