An antenna system includes: a plurality of antennas; a switching unit, having a plurality of switches, wherein each of the plurality of switches and the corresponding antenna are in a conducting state or in a non-conducting state; a communication unit, connected with each of the plurality of switches of the switching unit, and coupled with the antennas, wherein the communication unit receives a reference value group of the corresponding antenna from the switch in the conducting state; and a control unit, connected with the switching unit and the communication unit, wherein the control unit receives the reference value group from the communication unit, and compares the reference value group with an threshold, to determine whether the reference value group conforms to a pre-determined condition or not, and outputs a restarting instruction to restart the switching unit when the reference value group does not satisfy the pre-determined condition.

Antenna system and restarting method thereof

The present invention provides an antenna structure. The antenna structure includes a main board, at least having a signal feeding portion; a bearing component, connected to the main board and at least having a protrusive portion; and an antenna, connected to the bearing component and at least having a pin portion, wherein the pin portion is disposed on the protrusive portion, and the signal feeding portion and the pin portion contact with each other.

Antenna structure

A handheld GPS device has a device body. A base band processor is installed in the device body. Three antennas with high directivity are respectively installed perpendicular to three surfaces of the device body for receiving GPS signals. A control device is coupled to the base band processor and the antennas with high directivity. At least two switches are respectively coupled to the control device and each of the three switches corresponds to one of the three antennas with high directivity. One of the switches enables the control device to permit the base band processor receiving GPS signal from the corresponding antenna with high directivity when the frame triggers one of the switches.

Handheld GPS device

Hand-held communication device includes a first housing, a rotation axle connected to the first housing in a rotatable manner, a second housing, an antenna installed inside the second housing, and a rod with one end connected to the rotation axle in a rotatable manner and the other end connected to the second housing. The antenna can be positioned to optimize radio frequency signal reception by rotating the rotation axle with respect to the first housing and rotating the rod with respect to the rotation axle.
