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 retaining ring structure for fixing a satellite antenna having a retaining ring integrally formed by stamping a metal piece. The retaining ring consists of a C-shaped body and two clamping pieces extending from a slot of the C-shaped body to the outside. A plurality of projecting pieces is axially formed by a stamping process from the external side toward the internal side such that the C-shaped body is properly contracted to grip the positioning rod when the clamping pieces are tightened with bolts. Meanwhile, the projecting pieces create a biting structure that bites the positioning rod such that the positioning rod is firmly held by the retaining ring to prevent the retaining ring from rotation on the positioning rod. Moreover, the structure in accordance with the invention can withstand the inertia toque created by the strong wind force acting on the receiving dished plate. Meanwhile, the receiving dished plate won't be rotated so that an accurate direction of the receiving dished plate as well as an improved quality of receiving the satellite signals can be ensured.
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 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:
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.
