Abstract: An antenna system and a signal transmission method are provided. The antenna system includes: an antenna array and a matching network, where an S parameter matrix of the matching network matches an S parameter matrix of the antenna array and the matching network is configured to perform pre-distortion on a to-be-transmitted signal or de-distortion on a received signal, and the antenna array is configured to transmit the pre-distorted to-be-transmitted signal. According to the antenna system and the signal transmission method provided in this application, pre-distortion may be performed on a signal that needs to be transmitted by the antenna array or de-distortion may be performed on a signal received by the antenna array, so as to configure energy that is coupled from each antenna array element to an adjacent antenna array element, thereby reducing a coupling effect between antenna array elements.
