Embodiment approach 1

[0083] (Outline of millimeter wave transmission and reception system 100 )

[0084] figure 1 It is an example diagram showing a schematic configuration of the millimeter wave transmission and reception system 100 .

[0085] like figure 1 As shown, the millimeter wave transceiver system 100 is set indoors, and includes a transmitting device 1 for transmitting radio waves in the millimeter wave band (hereinafter referred to as "millimeter waves"), and a transmission signal (millimeter wave) for transmitting to the transmitting device 1. ) the reflector 41 for reflection and the receiving device 2 for receiving the transmission signal (millimeter wave) reflected by the reflector 41 .

[0086] In this embodiment, a millimeter-wave video multiplex transmission system is used as an example for description. The millimeter-wave transceiver system 100 is installed in a living room, etc., for example, and up-converts broadcast waves such as digital broadcasting into signals in the 6...

example 2

[0167] Next, other circuit examples of the transmitting device 1 and the receiving device 2 will be described.

[0168] Image 6 is a configuration diagram showing the millimeter wave transmission and reception system 100 .

[0169] Compared with the configuration of the millimeter wave transmission and reception system 100 described in the detailed configuration example 1, in the detailed configuration example 2, the transmitting device 1 is completely the same as the detailed configuration example 1, and the receiving device 2b is different from the detailed configuration example 1. The receiving device 2b is different from the receiving device 2 in that it down-converts the wireless multiple signal 73 input from the receiving antenna 14 according to the local oscillation signal 73b (frequency fLO3 ), thereby generating the second intermediate frequency multiple signal 74b, wherein the local oscillator The signal 73 b is an output signal of the local oscillator 8 , and incl...

Embodiment approach 2

[0191] Below, according to Figure 7 , Figure 8 , Embodiment 2 will be described.

[0192] Figure 7 It is a schematic diagram showing the configuration of the millimeter wave transmission and reception system 200 according to the second embodiment. Figure 8 yes means Figure 7 A side view of the structure of the reflector in .

[0193] Components that are the same as those in Embodiment 1 are also assigned the same component symbols here, and description thereof will be omitted.

[0194] Hereinafter, parts different from Embodiment 1 will be described. In Embodiment 1, reflective plate 41 (reflective plate 41 a , reflective plate 41 b ) with reflective surface 43 being flat was described, but reflective plate 41 c of this embodiment differs from the above in that reflective surface 43 c has a concave shape.

[0195] In addition, for example, a tripod 101 is used to fix the transmitter 1 on an appliance 102 such as a cabinet.

[0196] The level adjuster / power supply 5...

Abstract

A millimeter wave transceiving system 100 for transmitting and receiving a millimeter wave includes a transmitting apparatus 1 for transmitting a millimeter wave, a reflecting plate 41 for reflecting a millimeter wave transmitted from the transmitting apparatus 1, and a receiving apparatus 2 for receiving a millimeter wave reflected by the reflecting plate 41. The reflecting plate 41 includes a metal plate, a metal sheet, or a metal film, as a reflecting surface 43 for reflecting a millimeter wave. This makes it possible to realize a millimeter wave transceiving system which allows an easy installation.

Description

technical field [0001] The invention relates to a millimeter wave transceiving system for wirelessly transmitting and receiving broadcast waves in the millimeter wave band. Background technique [0002] As a conventional wireless communication system, for example, Patent Document 1 discloses an indoor wireless communication system, and Patent Document 2 discloses an optical space transmission system. [0003] Figure 12 It is a schematic diagram showing the configuration of an indoor wireless communication system disclosed in Patent Document 1 as a first conventional example. [0004] like Figure 12 As shown, the signal sent by the main machine 810 and the main machine antenna 820 arranged on the wall near the ceiling is transmitted along the transmission path 890 that is basically parallel to the ceiling and reaches the secondary reflector 850. After being reflected by the secondary reflector 850, the signal The conveying direction changes to the conveying direction towar...
