Abstract: A three-band antenna device with resonance generation includes a dielectric layer having an upper surface and a lower surface, a grounding element, a first radiating element, and a second radiating element. The first radiating element is arranged on the upper surface for providing a first frequency band. The second radiating element is arranged on the lower surface and stacked below the first radiating element via the dielectric layer for providing a second frequency band, so as to generate a parasitic capacitance therebetween. A third frequency band is provided by the resonance of the parasitic capacitance and the parasitic inductance in the second radiating element.

Abstract: An operating apparatus for a hand-held electronic apparatus includes a motion sensor, an analog to digital converting module and a processing unit. The motion sensor is utilized for sensing a motion track of the hand-held electronic apparatus to generate an analog sensing signal. The analog to digital converting module is coupled to the motion sensor, and is utilized for converting the analog sensing signal into a digital sensing signal. The processing unit is coupled to the analog to digital converting module, and is utilized for executing a multimedia motion control software to determine whether the motion track of the hand-held electronic apparatus corresponds to a predetermined track according to the digital sensing signal. Furthermore, the processing unit executes at least one predetermined function corresponding to the predetermined track from a plurality of predetermined functions when determining that the motion track corresponds to the predetermined track.

Abstract: A multi-antenna module includes a plurality of antennas for receiving or transmitting a plurality of wireless signals. When one of the antennas is utilized to receive a satellite signal, a position of the antenna is disposed higher than those of the other antennas in the multi-antenna module; when one of the antennas is utilized to receive or transmit a WPAN or WLAN signal, the antenna is disposed on one side of the multi-antenna module; and when one of the antennas is utilized to receive or transmit a WMAN or WWAN signal, a position of the antenna is disposed lower than those of the other antennas in the multi-antenna module. Through planning the disposition of the antennas and the distance between two antennas, the present invention can reduce signal interference problems and achieve better signal isolation, thereby effectively integrating functions of various wireless communication systems into the multi-antenna module.
