Abstract: Disclosed is an antenna device for transceiving a wireless signal. The antenna device includes an antenna element adapted to establish a radiation pattern during transceiving the wireless signal; an antenna signal feeding line coupling to the antenna element for feeding the wireless signals transceived by the antenna element; and at least one radiation pattern adjustment element arranged at an adjacent position with respect to the antenna element and within the established radiation pattern of the antenna element to adjust the radiation pattern of the antenna element.

Abstract: Disclosed is an antenna device having a substrate, an antenna element for transceiving a wireless signal, an antenna signal feeding line for feeding the wireless signal, and an ion-implanted resonant pattern, which includes a first coupling pattern implanted in the substrate by an Ion-implantation process and a second coupling pattern formed at a position corresponding to the first coupling pattern with a predetermined distance therebetween, formed at an adjacent position with respect to the antenna element. As the antenna element transceives the wireless signal of the predetermined radiation frequency and generates an induction voltage, the first coupling pattern and the second coupling pattern each generates a coupled induction voltage and a capacitance therebetween, hence forming a resonance with the antenna element.

Abstract: Disclosed is a coupling antenna device for transceiving a plurality of wireless signals with multiple radiation frequencies. The coupling antenna device includes an antenna pattern having a plurality of adjacent resonating sectors, each of the resonating sectors having a length determined by a specific radiation frequency responsive to one of the wireless signals.

Abstract: An inverted-F antenna comprises a microwave plate, a dielectric substrate, a radiating metal sheet, a ground surface, a shorting metal strip, and a feeding metal strip. The radiating metal sheet comprises a connecting metal sheet, first, second, and third child radiating metal sheets, a matching metal sheet, a slot, a shorting point, and a feeding point. The first child radiating metal sheet is for forming a low frequency operating mode. The second child radiating metal sheet is for forming a high frequency operating mode. The third child radiating metal sheet is for adjusting operating frequency and bandwidth of the second operating mode. The slot, the shorting point, and the feeding point are for adjusting impedance matching. The grounding surface is for increasing the operating bandwidth of the low frequency operating mode. The shorting metal sheet and the feeding metal sheet are for grounding the antenna and signal transmission.

Abstract: Provided is dual-band inverted-F antenna for GSM, DCS, and PCS bands comprising a primary radiating member including integral first and second metallic strips, a feeding point, and a first shorting point wherein a long current path is created in the first strip such that the antenna can operate in a first low frequency operating mode, and a shorting current path is created in the second strip such that the antenna can operate in a second high frequency operating mode; a secondary radiating member comprising a second shorting point; a branch line shorting strip having one grounded end and a bifurcation including a first branch connected to the first shorting point and a second branch connected to the second shorting point; and a feeding member interconnected the feeding point and a signal source. Operating frequencies of the antenna are 90 MHz and 300 MHz respectively when it operates in 3.5:1 VSWR impedance bandwidth.

Abstract: A music playing method and disc drive apparatus thereof, for reading a compact disc (CD). The disc drive apparatus includes an interface electrically connected to the host, a decoder, and a reading unit for identifying the CD with an audio format or an encoded audio format and reporting to the host through the interface. The host sends out a command to the disc drive apparatus for outputting an analog audio signal. If the CD is the audio format, the reading unit outputs a track of the CD as a first analog audio signal. If the CD is the encoded audio format, the reading unit outputs a first encoded audio file as a first analog audio signal by the decoder.
