| titleOfInvention | Adjustable multi-band antenna and antenna debugging method |
| abstract | The invention discloses an adjustable multi-band antenna and an antenna debugging method. The tunable multiband antenna of the present invention comprises: the antenna comprises a first antenna unit, a second antenna unit, a first antenna impedance unit, a second antenna impedance unit, a first control unit, an antenna matching unit and a second control unit; the first antenna unit and the first antenna impedance unit are connected with the first control unit, and the first control unit is connected with the radio frequency circuit; the second antenna unit is connected with the second control unit, the second control unit is connected with the first control unit through the antenna matching unit and is grounded through the second antenna impedance unit; the first control unit is used for controlling the conduction of the first antenna unit and the radio frequency circuit and the conduction of the second antenna unit and the radio frequency circuit; the second control unit is used for controlling the connection of the second antenna unit with the antenna matching unit and the second antenna impedance unit; the antenna of the invention can expand the bandwidth of the antenna on the premise of not increasing the volume of the antenna. |
