Abstract: 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.

Abstract: A transceiver module for a satellite antenna comprises a base and a cover. The base includes a transducer extending between a first end plate and a second end plate in a first direction, a first filter portion including a number or first grooves extending in the first direction and arranged along a second direction orthogonal to the first direction, and a waveguide to guide signals toward a third end plate. The cover serves as a second filter portion for the transceiver module and includes a number of second grooves arranged along the second direction. The base includes the transducer, the first filter portion and the waveguide as an integral member.

Abstract: An antenna mount for a satellite antenna comprises an adjustment plate with a first cam slot, a first bracket and a first cam. The first bracket includes a first base, a first sidewall extending from the first base and having a second cam slot aligned with the first cam slot, and a second sidewall extending in parallel with the first sidewall from the first base. The first cam is adapted to attach the adjustment plate to an inner surface of the first sidewall. The first cam includes a first shaft protruding from the first sidewall through the first and second cam slots and rotatable with respect to the first sidewall, and a first disc coupled with the first shaft and adapted to fit within the first cam slot so that the adjustment plate is rotatable with respect to the first sidewall as the first shaft is rotated from the exterior of the first sidewall.

Abstract: 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.

Abstract: A satellite antenna includes an antenna dish, a connecting arm, a pole, at least one clamp and a cover bracket. The antenna dish may include a front surface and a rear surface. The connecting arm has a first end and a second end, wherein the first end is coupled with the rear surface of the antenna dish. The pole may extend transversely with respect to the connecting arm and may include a channel extending from one end to the other end of the pole. The at least one clamp may each include a base with an opening that allows the pole to pass through. The cover bracket may include a front cover to seal the second end of the connecting arm, and a first cover integral with the front cover that includes a first side and a second side. The first cover may support the pole over the connecting arm on the first side and engage with the connecting arm with the second side.

Abstract: A filter unit comprises a cover and a base. The cover includes a number of first grooves, and the base includes a number of second grooves aligned with the first grooves. At least one of the cover or the base includes an alloy of zinc and aluminum, wherein the weight percentage of zinc is greater than that of aluminum.

Abstract: 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.

Abstract: A method for satellite lock-on in an antenna system by channel selection is initiated by receiving a channel selection signal. The channel selection signal is flagged to retrieve satellite parameters corresponding to the selected channel from a pre-stored satellite channel table which provides a correlation among the channels, the bands and the satellite coordinates. Then, according to the retrieved satellite parameters, an antenna control signal and thus a drive signal are generated orderly to drive the antenna to direct at the satellite responsible to the selected channel.
