Abstract:
A filter assembly, an antenna apparatus and a base station system. The filter assembly comprises a dielectric slab (302). A filter (301), a first connector (303) and a second connector (304) are arranged on the dielectric slab (302). An input signal line (305) is arranged in the dielectric slab (302). One end of the input signal line (305) is connected to an input end (301a) of the filter (301); and the other end of the input signal line (305) is connected to the first connector (303). An output end (301b) of the filter (301) is connected to the second connector (304) by means of an output signal line (306). The filter assembly further comprises a signal shielding structure (307). The signal shielding structure (307) is provided with a shielding cavity. At least part of the dielectric slab (302) and the input signal line (305) are located in the shielding cavity; and the output signal line (306) is located outside the shielding cavity, where the input signal line (305) is located.
