Embodiment Construction

[0039] like Figure 1 to Figure 6 As shown, according to the present invention, the feed-back satellite TV antenna includes a divergent element 200 with electromagnetic wave divergence function arranged in front of the feed source 1, and a metamaterial panel 100 arranged in front of the divergent element 200, and the metamaterial panel 100 includes a core Layer 10, 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 hole structures 12 arranged on the substrate 13, the core layer sheet According to the refractive index distribution, the layer 11 can be divided into a circular area Y located in the middle and a plurality of annular areas distributed around the circular area Y and concentric with the circular area (respectively H1, H2, H3, H4, H5 represent), the refractive index at the same radius in the circular area Y and the annular area is the same, and the refractive index gradua...

Abstract

The invention discloses a fallback type satellite television antenna which comprises a diffusing element and a metamaterial panel. The metamaterial panel comprises a core layer which comprises a core layer sheet layer, the core layer sheet layer comprises a circular region and a plurality of ring regions surrounding the circular region, refractive indexes at the position with same radii of the circular region and the ring regions are same, the refractive indexes gradually decrease along increase of the radii in respective region of the circular region and the ring regions, a minimum value of the refractive index of the circular region is smaller than a maximum value of the refractive index of the adjacent ring region, and a minimum value of the refractive index of the ring region on the inside of two adjacent ring regions is smaller than a maximum value of the refractive index of the ring region on the outside of the two adjacent ring regions. By means of the fallback type satellite television antenna, the sheet fallback type satellite television antenna replaces a traditional parabolic antenna and is easy to manufacture and low in cost. In addition, the invention further discloses a satellite television receiving system with the fallback type satellite television antenna.

Description

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