摘要： A Low Noise Block downconverter (LNB) with high isolation, and more particularly, to a low-noise-block downconverter design for horizontal wave and vertical wave of a linear polarization; wherein, a horizontal probe and a vertical probe are directly set on a printed circuit board to receive the aforesaid waves; a waveguide chamber of the horizontal probe is divided into two chambers, a front chamber and a back chamber; a waveguide chamber of the vertical probe is transversely extended from a side waveguide, and the waveguide chamber of the vertical probe is also divided into two chambers; thereby the horizontal and vertical probe respectively receives the waves when facing to the rear side of the waveguide chambers for separating the horizontal and vertical wave and reducing the coupling of each other; thus, increasing the isolation and preventing the mutual interference of the horizontal and vertical wave.

摘要： An antenna system and a corresponding method for satellite lock-on applied to vehicles automatically lock on at least one satellite in the space by means of a lock-on signal. The technique features on a scan driving signal that initiates a space scan of the antenna system so as to obtain a scan data. According to peak values of the scan data, coordinates of a plurality of satellites in the space are realized and individually recorded. Then, after receiving a lock-on signal, the satellite coordinate of the satellite to be locked is retrieved so as to drive the antenna to point at the satellite to be locked.

摘要： A mobile digital signal transceiving device comprises a multimedia interface, a processing unit and a radio frequency (RF) signal transmitter. The multimedia interface reads at least one multimedia data stored in at least one multimedia memory device. The processing unit transfers the multimedia data into a terrestrial broadcast data in a digital video broadcasting-terrestrial (DVB-T) data format, and modulates the terrestrial broadcast data in order to generate an RF signal. The RF signal transmitter transmits the RF signal so that the RF signal may be received by at least one mobile multimedia device.
