Abstract: The present disclosure provides a base station. The base station includes a multi-function board, a radome and at least one antenna element. The radome is configured to cover the multi-function board. The at least one antenna element is provided between the multi-function board and the radome. The multi-function board is configured to integrate with at least two of functions of a radio board, an EMC cover, an AC board, an antenna reflector, and an Antenna board.

Abstract: Embodiments of the present disclosure provide an antenna device and a base station comprising the same. The antenna device may comprise an antenna array with a radiation pattern including a main lobe and a back lobe; and a first reflector able to be configured to reflect a first part of energy of the back lobe to at least one direction different from a direction of the main lobe.

Abstract: Embodiments of the disclosure provide an antenna filter unit and a radio unit. The antenna filter unit includes a radiation unit and a cavity filter coupled to the radiation unit. The radiation unit is arranged on an outer side of a wall of a cavity of the cavity filter. At least a part of the wall is also arranged as a reflection plate for the radiation unit. The radio unit includes the above-mentioned antenna filter unit and a radio circuit board. According to the antenna filter unit and the radio unit provided by embodiments of the disclosure, the number and volume of elements in a radio system are reduced, the degree of integration can be improved, the weight and installation space are reduced, and the costs are reduced.
