摘要： This application provides an antenna and a communication system. The antenna includes a front mounting surface, a side mounting surface, a front radiating element array, and a side radiating element array. The front radiating element array is mounted on the front mounting surface, and the side radiating element array is mounted on the side mounting surface. An included angle on a side away from the front radiating element array is a first included angle, and the first included angle is less than 180°. This helps reduce wind load of the antenna, improve coverage of the antenna, and improve performance of the antenna. One end of a circuit module is connected to an antenna port connected to the front radiating element array and an antenna port connected to the side radiating element array, and another end of the circuit module is configured to connect to radio frequency ports. The circuit module enables the front radiating element array and the side radiating element array to be connected to a same drive end, so that both the front radiating element array and the side radiating element array can be driven. At least one antenna port is electrically connected to at least two of the plurality of radio frequency ports through the circuit module, to reallocate power input by the radio frequency port.

摘要： 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; a first operating frequency band of the first antenna module is different from a second operating frequency band of the second antenna module; and the second antenna module may transmit an electromagnetic wave of the first operating frequency band, and radiate or receive an electromagnetic wave of the second operating frequency band. The solutions in this application can enable the base station system to implement multi-band coverage. The antenna module in the system canoperate independently without affecting each other, and can be mounted and disassembled separately.
