Antenna structure and head mounted display device

A head mounted display device, comprising:

• a main body;
• two temples, respectively disposed on opposite sides of the main body;
• and
• at least one antenna structure, disposed in at least one of the two temples, and comprises:
• a first structure body, receiving a reference ground voltage;
• a second structure body, coupled to the first structure body, the second structure body comprises a conductive part, a shaft sleeves part and a shaft body, the shaft body passes through the shaft sleeves part, the shaft body, as a radiator, is electronically coupled to the conductive part, and the conductive part is coupled to a feed point;
• and
• a feeding element, coupled to the feed point and the first structure body, and is used for transmitting and receiving a radio frequency signal,
• wherein the shaft body has an axial direction, and the length of the shaft body along the axial direction is ½ or ¼ of the wavelength of the radio frequency signal.
