Embodiment Construction
[0045] Such as figure 1 As shown, it is a structural schematic diagram of a bias feed-back satellite TV antenna according to an embodiment of the present invention, and the bias feed-back satellite TV antenna includes a metamaterial panel 100, which includes a core layer 10 and two opposite core layers. Impedance matching layer 20 on the side surface. The metamaterial panel 100 can be in any shape such as square, circular or oval, such as figure 1 The metamaterial panel 100 shown in is square.
[0046] Please continue to refer Figure 2 to Figure 4 , the core layer 10 includes a plurality of stacked core layer sheets 11 with the same thickness and the same refractive index distribution. In this embodiment, the core layer 10 includes two core layer sheets 11, such as figure 1 shown. Each core layer sheet 11 includes a first base material 131 in sheet form, a second base material 132 and a plurality of artificial microstructures placed between the first base material 131 an...

The invention discloses a bias feedback type satellite television antenna. A satellite television signal which is positioned on one side of the antenna penetrates through the antenna and is received by a satellite television signal transceiver which is positioned on the other side of the antenna, or the satellite television signal which is generated by the satellite television signal transceiver on one side of the antenna penetrates through the antenna and is sent from the other side of the antenna. The bias feedback type satellite television antenna comprises a metamaterial panel which is fixed on a window of a house, wherein the metamaterial panel comprises a core layer and an impedance matching layer which is arranged on a satellite television signal incidence side of the core layer; the core layer comprises two core layer laminates which are equal in thickness and equal in refractive index distribution; and each core layer laminate comprises a first base material and a second base material, which are laminated together and sheet-like, and a plurality of artificial microstructures which are arranged between the first base material and the second base material. According to the bias feedback type satellite television antenna provided by the invention, the conventional parabolic antenna is replaced by the sheet-like metamaterial panel. The antenna is easy to manufacture and process, low in cost and high in product consistency. The invention also provides a satellite television transmitting and receiving system.
Description
technical field [0001] The invention relates to the communication field, and more specifically relates to a biased feed-back satellite TV antenna and a satellite TV transceiver system thereof. Background technique [0002] The traditional satellite TV receiving system is a satellite ground receiving station composed of a parabolic antenna, a tuner, and a signal converter. The parabolic antenna is responsible for reflecting the satellite signal into the tuner at the focal point. The high-frequency head LNB (also known as the down-converter) is to down-frequency and amplify the satellite signal and then transmit it to the signal converter. Generally, it can be divided into C-band frequency LNB (3.7GHz-4.2GHz, 18-21V) and Ku-band frequency LNB (10.7GHz-12.75GHz, 12-14V). The working process of LNB is to first amplify the satellite high-frequency signal to hundreds of thousands of times, and then use the local oscillator circuit to convert the high-frequency signal to an inter...
