Embodiment Construction

[0036] Such as Figure 1 to Figure 6 As shown, according to the present invention, the offset feed type satellite TV antenna includes a metamaterial panel 100 arranged behind the feed source 1, and the metamaterial panel 100 includes a core layer 10 and a reflector 200 arranged on one side surface of the core layer 10, so The core layer 10 includes at least one core layer sheet 11, the core layer sheet 11 includes a sheet-shaped substrate 13 and a plurality of artificial hole structures 12 arranged on the substrate 13, with a certain point as the center of the circle, the The refractive index at the same radius on the core layer is the same. As the radius increases, the refractive index gradually decreases. The centers coincide, that is, the feed source is not on the central axis of the core layer, which realizes the offset feeding of the antenna. Both the feed source 1 and the metamaterial panel 100 are supported by brackets, which are not shown in the figure, which is not t...

Abstract

The invention discloses an offset satellite television antenna which comprises a metamaterial panel arranged at the back of a feed source. The metamaterial panel comprises a core layer and a reflective plate arranged on one side of the core layer. The core layer comprises at least one laminated layer, each laminated layer comprises a laminated substrate and a plurality of artificial micropore structures arranged on the substrate. Refractive indexes, at the position with the same radius, of the laminated layers of the core layer, are the same around a fixed point as a circle center, and are reduced gradually along with increase of the radius. A link between the circle center and the feed source is perpendicular to the corresponding laminated layer of the core layer, and does not coincide with the center of the corresponding laminated layer of the core layer. Since the antenna with the laminated metamaterial panel substitutes for the conventional parabola antenna, the offset satellite television antenna is easy to manufacture and process and low-cost. The invention further provides a satellite television receiving system with the offset satellite television antenna.

Description

technical field [0001] The invention relates to the communication field, and more specifically, relates to a bias-feed satellite TV antenna and a satellite TV receiving system thereof. Background technique [0002] The traditional satellite TV receiving system is a satellite ground receiving station composed of parabolic antenna, feed source, tuner and satellite receiver. The parabolic dish is responsible for reflecting the satellite signal into the feed and tuner at the focal point. The feed source is a horn set at the focal point of the parabolic antenna to collect satellite signals, also known as a corrugated horn. There are two main functions: one is to collect the electromagnetic wave signal received by the antenna, transform it into a signal voltage, and supply it to the tuner. The second is to perform polarization conversion on the received electromagnetic waves. The high-frequency head LNB (also known as the down-converter) is to down-frequency and amplify the sat...
