Abstract

An antenna module and a signal-processing module using the antenna module to process a plurality of wireless signals are proposed. The signal-processing module includes the antenna module, a first processing circuit and a second processing circuit. The antenna module includes at least a first antenna, at least a second antenna and a shielding portion. The first antenna is utilized to transmit or receive signals corresponding to a first wireless communication standard, the second antenna is utilized to transmit or receive signals corresponding to a second wireless communication standard, and the shielding portion is disposed between the first antenna and the second antenna. The first processing circuit is coupled to the first antenna for processing signals of the first antenna, and the second processing circuit is coupled to the second antenna for processing signals of the second antenna.
