1. A signal feeding assembly, comprising:
a substrate;
a transmission unit positioned on the substrate;
a switching unit positioned on the substrate and comprising a control end, a common end, and at least two switching output ends, wherein the control end and the common end are electrically connected to the transmission unit to transmit and receive baseband signals and radio frequency signals through the transmission unit; and
a signal coupling unit positioned on the substrate, wherein the signal coupling unit is spaced apart from a radiation element to transmit and receive the baseband signals and the radio frequency signals through the radiation element to generate a plurality of radiation modes;
wherein the signal coupling unit comprises at least two coupling pieces, each of the coupling pieces is electrically connected to a switching output end, the switching unit controls a switching of the coupling pieces through the switching output ends to switch the plurality of radiation modes.
