Abstract: An antenna system, a feeding network reconfiguration method, and an apparatus is disclosed. The antenna system may include an antenna array, a reconfigurable network unit, a control unit, and K radio frequency channels. The antenna array may include L antenna subarrays, and the reconfigurable network unit may divide the L antenna subarrays into M antenna subarray groups, and separately connect the M antenna subarray groups to the K radio frequency channels; any one of the K radio frequency channels may perform signal processing on a signal received by a connected antenna subarray group and/or a to-be-transmitted signal; and the control unit may control the reconfigurable network unit to adjust a mapping relationship between an antenna subarray group connected to each radio frequency channel and the antenna subarrays.
