Abstract

The present disclosure relates to an antenna module and a terminal device. The antenna module comprises: a first radiator; a feed point located on the first radiator; a second radiator arranged apart from the first radiator; wherein when the first radiator and the second radiator jointly receive and transmit wireless signals after being coupled, the first radiator and the second radiator have the same current flow direction. In the embodiment of the present disclosure, when receiving and transmitting wireless signals, the total current of the antenna module does not appear to be cancelled out due to opposite current directions, thereby being able to increase the phase of the current in the antenna module and expand the working bandwidth of the antenna module.
