Abstract
The invention discloses a global positioning system (GPS) antenna structure capable of elastically changing a position. The GPS antenna structure is used for a GPS navigator, and comprises a GPS antenna module, two grounding tracks and a radio frequency input terminal. The GPS antenna module comprises an antenna body. The two sides of the bottom surface of the antenna body are provided with a bracket respectively. The bottom end of each bracket is provided with a pulley. Each pulley is electrically connected with a grounding terminal of the antenna body by the brackets respectively. A radio frequency signal wire is arranged at a position, close to the center, on the bottom surface of the antenna body. The two grounding tracks are arranged on at least one side edge of the GPS navigator. The two pulleys are accommodated in the grounding tracks respectively. The radio frequency input terminal is arranged between the two grounding tracks of the GPS navigator, and is in signal connection with the radio frequency signal wire. Due to the adoption of the grounding tracks and the pulleys, the GPS antenna structure can regulate the receiving direction of the antenna body to achieve adaptability to the change of the GPS navigator in different display directions.
