Embodiment Construction

[0056] like Figure 1 to Figure 5 As shown, it is a structural schematic diagram of an offset feed satellite TV antenna according to the first embodiment of the present invention. The offset feed satellite TV antenna includes a metamaterial panel 100 fixedly attached to the vertical wall NQ, and the metamaterial panel The lower edge of 100 is at the same level as the upper end of the feed source 1, and the metamaterial panel 100 includes a reflective layer 200 with one side surface set against the wall, a core layer 10 set on the other side surface of the reflective layer 200, and another set of the core layer. Impedance matching layer 20 on one side surface. Feed 1 is a traditional corrugated horn, which has different choices depending on the polarization of the TV signal of the satellite. For example, the TV signal of Zhongxing No. The source should be a corrugated horn with dual circular polarization. In addition, in the present invention, the reflective layer is a metal ...

Abstract

The invention discloses an offset-fed satellite television antenna which comprises a metamaterial panel fixedly attached to a vertical wall. The lower edge of the metamaterial panel and the upper end of a feed source are positioned on the same level. The metamaterial panel comprises a reflecting layer and a core layer, wherein one lateral surface of the reflecting layer is close to the wall, the core layer is arranged on the other lateral surface of the reflecting layer and comprises a plurality of slice layers, each slice layer of the core layer comprises a first sheet base material and a plurality of first artificial microstructures arranged on the first base material, and the antenna can receive a television signal of a specific satellite through the special design of refractive index distribution of the slice layers of the core layer. According to the offset-fed satellite television antenna, a traditional parabolic antenna is replaced by the sheet metamaterial panel, so that manufacturing and processing are easier, cost is lower, and consistency of products is high.

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...
