Antenna device

The utility model relates to an antenna device which is suitable for being combined on an electronic device and enables the electronic device to be in wireless communication transmission with a remote control device. The antenna device comprises a circuit board, an antenna unit printed on the circuit board, and a metal wire unit arranged on the circuit board and connected with the antenna unit. The antenna unit is provided with a first end and a second end. The antenna unit has a working frequency. The metal wire unit is provided with two connecting ends. By means of the design that the connecting ends of the metal wire unit are respectively connected with the first end and the second end of the antenna unit, and the antenna unit is matched with the metal wire unit to adjust the working frequency of the antenna unit to the center frequency. The overall wavelength can be increased by adjusting the length of the metal wire unit to be matched with the layout design of the antenna unit, so that the required frequ
