Embodiment Construction

[0039] Such as Figure 1 to Figure 6 As shown, according to the present invention, the feed-forward satellite TV antenna includes a divergent element 200 with an electromagnetic wave divergence function arranged behind the feed source 1, and a metamaterial panel 100 arranged behind the divergent element 200, and the metamaterial panel 100 includes a core layer 10 and a reflection plate 200 arranged on one side surface of the 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 is arranged on the substrate 13 According to the refractive index distribution, the core layer 11 can be divided into a circular area Y located in the middle and a plurality of artificial hole structures 12 distributed around the circular area Y and concentric with the circular area. Annular area (respectively represented by H1, H2, H3, H4, H5 in the figure), the refractive index at the same radius in the circular area Y...

Abstract

The invention discloses a feed-forward satellite television antenna which comprises a divergence element and a metamaterial panel. The metamaterial panel comprises a reflector and a core layer, and the core layer comprises core layer slices. Each core layer slice comprises a circular region and a plurality of annular regions distributed around the circular region, the refractive index of an optional position of the circular region is identical to the refractive index of an optional position, with the radius identical to that of the optional position of the circular region, of each annular region, the refractive index of each of the circular region and the annular regions is gradually decreased along with increase of the radius of each of the circular region and the annular regions, the minimum refractive index of the circular region is smaller than the maximum refractive index of each annular region adjacent to the circular region, and the minimum refractive index of the inner annular region of each two adjacent annular regions is smaller than the maximum refractive index of the outer annular region of the two adjacent annular regions. The platy metamaterial panel replaces the traditional parabolic antenna, and the feed-forward satellite television antenna is easy to manufacture and process and low in cost. In addition, the invention further provides a satellite television receiving system with the feed-forward 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 ...
