Two-shaft hinge antenna and foldable electronic device using the same

A two-shaft hinge antenna, comprising:

• a major conductor provided with stretching arms on both sides thereof;
• a first rotating element configured to be mounted to the stretching arm on a side of the major conductor, wherein the first rotating element comprises:
• a first vice conductor, a stretching arm on a side thereof is provided with a first fitting hole;
• a torque device including a rotating shaft and a plurality of fastening elements, wherein one end of the rotating shaft is mounted to the major conductor with a first fastening element, while the other end thereof penetrates the first fitting hole of the first vice conductor for mounting the first vice conductor to the torque device;
• and
• a second rotating element configured to be mounted to the stretching arm on the other side of the major conductor, wherein the second rotating element comprises:
• a signal feeding line configured to transmit a high frequency signal and having a positive end signal lead and a negative end signal lead;
• a microwave base plate having a signal feed-in section and a grounding section, the signal feed-in section including a signal pad electrically connected to the positive end signal lead of the signal feeding line, and the grounding section including a fixing pad for fixing the negative end signal lead of the signal feeding line to the grounding section;
• and
• a connection device, one end thereof being connected to the signal pad of the microwave base plate, while the other end thereof being connected to the major conductor for transmitting the high frequency signal to the major conductor, and further to the torque device connected to the major conductor for forming an antenna loop together with the first vice conductor.

A foldable electronic device, comprising at least a rotating mechanism, a first housing and a second housing, the rotating mechanism including an accommodating space and a two-shaft hinge antenna disposed in the accommodating space, the rotating mechanism enabling the first housing to be rotatable with respect to the second housing, wherein the two-shaft hinge antenna comprises:

• a major conductor connected to the first housing and provided with opposing stretching arms on both sides thereof;
• a first rotating element configured to be mounted to the stretching arm on a side of the major conductor, wherein the first rotating element comprises:
• a first vice conductor, a stretching arm on a side thereof is provided with a first fitting hole;
• a torque device including a rotating shaft and a plurality of fastening elements, wherein one end of the rotating shaft is mounted to the major conductor with a first fastening element, while the other end thereof penetrates the first fitting hole of the first vice conductor for mounting the first vice conductor to the torque device;
• and
• a second rotating element configured to be mounted to the stretching arm on the other side of the major conductor.
