Abstract

Disclosed are a wireless signal transmission device and a signal receiver thereof. The wireless signal transmission device comprises a reflection surface and the signal receiver. The reflection surface is used for receiving a wireless signal. The signal receiver receives the wireless signal reflected on the reflection surface. The signal receiver comprises a receiver main body, a waveguide tube, a transmission unit and a dielectric slice. The waveguide tube comprises an opening end and a connection end. The connection end of the waveguide tube is connected with the receiver main body. The transmission unit is arranged in the waveguide tube and close to the connection end. The transmission unit is used for receiving the wireless signal. The dielectric slice is arranged in the waveguide tube and comprises a first section part and a second section part, wherein the first section part is close to the transmission unit and the second section part is close to the opening end, the first section part is provided with a first dielectric constant and the second section part is provided with a second dielectric constant. The first dielectric constant is smaller than the second dielectric constant. According to the wireless signal transmission device and the signal receiver thereof, noise coefficient and signal insulation are obviously improved.

Description

technical field [0001] The invention relates to a wireless signal transmission device and a signal receiver thereof, in particular to a wireless signal transmission device for transmitting circularly polarized wireless signals and a signal receiver thereof. Background technique [0002] In the known circular polarization satellite receiver, a medium sheet is inserted into the linear polarization signal receiver to change the linear polarization signal receiver into a circular polarization signal receiver. However, inserting a dielectric sheet into a linearly polarized signal receiver will reduce the signal isolation (Cx-pol, which is defined as co-polarization (Copolization, hereinafter abbreviated as Copol) and cross-polarization (Cross-polarization, hereinafter Abbreviated as the ratio of Xpol), thus reducing the signal transmission effect of the circularly polarized satellite receiver. [0003] Therefore, it is necessary to provide a wireless signal transmission device a...
