Embodiment Construction

[0038] Such as Figure 1 to Figure 5 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 microstructures 12 arranged on the substrate 13, the core layer sheet The refractive index of the layer 11 is distributed circularly with its center as the center, 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 l...

Abstract

The present disclosure relates to a metamaterial for diverging an electromagnetic wave, which comprises at least one metamaterial sheet layer. Refractive indices of the metamaterial sheet layer are distributed in a circular form with a center of the metamaterial sheet layer, and the refractive indices remain unchanged at a same radius and increase gradually with the radius. The present disclosure changes electromagnetic parameters at each point of the metamaterial through punching or by attaching man-made microstructures so that the electromagnetic wave can be diverged after passing through the metamaterial. The metamaterial of the present disclosure features a simple manufacturing process and a low cost, and is easy to be implemented. Moreover, the metamaterial of the present disclosure has small dimensions and does not occupy a large space, so it is easy to miniaturize apparatuses made ofthe metamaterial of the present disclosure.

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...
