Embodiment Construction

[0031] Such as Figure 1 to Figure 5 As shown, according to the present invention, the feedforward 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 of the core layer. The core layer 10 includes at least one core layer sheet 11, the core layer sheet includes a sheet-shaped substrate 13 and a plurality of artificial microstructures 12 arranged on the substrate 13, the refraction of the core layer sheet 11 The refractive index is distributed in a circle with its center as the center, and the refractive index at the same radius is the same, and the refractive index gradually decreases with the increase of the radius. In the present invention, the feed source 1 is arranged on the central axis of the metamaterial panel, that is, the line connecting the feed source and the center of the core layer sheet 11 coincides with the central axis of the met...

Abstract

The invention discloses a feed-forward type satellite television antenna, which comprises a metamaterial panel arranged behind a feed source. The metamaterial panel consists of a core layer and a reflector arranged on the surface of one side of the core layer, the core layer comprises at least one core layer slice layer, each core layer slice layer comprises a flaky base material and a plurality of artificial micro-structures, refractive indexes of each core layer slice layer are circularly distributed, and the refractive indexes of positions, with identical radiuses, of each core layer slicelayer are identical, and are gradually reduced along with increase of the radiuses. The flaky metamaterial panel replaces a traditional parabolic antenna, and accordingly the feed-forward type satellite television antenna is easy in manufacture and processing and low in cost. In addition, the invention provides a satellite television receiving system comprising the feed-forward type satellite television antenna.

Description

technical field [0001] The invention relates to the communication field, and more specifically, relates to a feed-forward 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 ...
