Title:

SIGNAL TRANSCEIVING DEVICE, AND BASE STATION

Document Type and Number:

WIPO Patent Application WO/2019/095691

Kind Code:

A1

Abstract:

Disclosed is a signal transceiving device, comprising: at least one plug-in card and a backplate, wherein the plug-in card comprises two waveguide plates, a multi-layer circuit board sandwiched between the two waveguide plates, an antenna array mounted on the two waveguide plates, and a first waveguide interface, a waveguide groove is disposed on one side of the two waveguide plates facing the multi-layer circuit board, and a metal layer corresponding to the waveguide groove is disposed on both sides of the multi-layer circuit board, correspondence means that the metal layer and the waveguide groove cooperate with each other to form a double-layer waveguide channel respectively located on both sides of the multi-layer circuit board and connected to the antenna array and the first waveguide interface, a second waveguide interface is disposed on the backboard; the waveguide connection between the plug-in card and the backplate are realized by means of docking between the first waveguide interface and the second waveguide interface. Disclosed are a signal transceiving device, and a base station. By means of the application, the integration degree of a waveguide structure is improved, the space utilization rate of a signal transceiving device is improved, and at the same time, heat dissipation of the signal transceiving device is facilitated.
