An integrated structure of an inkjet head and an antenna includes a metal heat dissipation board, a flexible (or rigid) circuit board and an antenna module. The metal heat dissipation has an elongated printing ribbon. The flexible (or rigid) circuit board is mounted on the metal heat dissipation board, and has one end electrically connected with the printing ribbon and the other end having a plurality of parallel circuits mounted thereon and connected to external control circuits. The antenna module is directly mounted on and electrically connected with the flexible (or rigid) circuit board. Given the integrated structure, the antenna module is effectively mounted on the inkjet head to reduce the size of the structure and lower the cost thereof.
