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] Such as 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. ) reflector 41 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 60 GHz band. This...

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, reflector 41 (reflector 41a, reflector 41b) with reflective surface 43 was described as flat, but reflector 41c of this embodiment differs from the above in that reflective surface 43c 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 is arranged on the top of the set 10...

Embodiment approach 3

[0201] Below, according to Figure 9 , Figure 10 (a), (b), Figure 11 (a), (b), for the difference in embodiment 3 figure 1 The structure of Embodiment 1 shown will be described.

[0202] Figure 9 It is a schematic diagram showing the configuration of the millimeter wave transmission and reception system 300 according to the third embodiment.

[0203] Figure 10 (a) means Figure 9 A side view of the structure of the reflector, Figure 10 (b) is a side view which shows the modification of the structure of a reflector.

[0204] Components that are the same as those in Embodiments 1 and 2 are also given the same component numbers here, and descriptions thereof are omitted.

[0205] Embodiment 3 differs from Embodiments 1 and 2 in the shape and number of reflecting plates.

[0206] Such as Figure 9 As shown, the level adjuster / power supply 5 is connected to the indoor broadcasting antenna terminal, and the transmitting device 1 is directly connected to the level adj...

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] Such as 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 to...
