Milliwave transmitting device, milliwave receiving device and milliwave transmission and reception system capable of simplifying wiring of a receiving system of terrestrial broadcasting service and satellite broadcasting service

Abstract

In conventionally receiving satellite broadcasting (BS, CS) and terrestrial broadcasting (VHF, UHF) services, transmitting the services to a plurality of TV receivers in an individual house results in complicated wiring and a community house is also limited in the number of installed TV receivers due to previously setting a distributor and thus requires an additional distributor to be installed when a TV receiver is additionally installed. The milliwave receiving and transmitting system of the present invention allows a broadcast signal to be transmitted and received indoors via indoor, wireless milliwave transmission without using any indoor wiring.

1 . An electrical appliance, comprising a milliwave-signal distributor and relay, said milliwave-signal distributor and relay including a receiving antenna, a distributor, and a plurality of transmitting antenna for changing a radiation direction.  
   
   
       2 . The electrical appliance according to  claim 1 , wherein said milliwave-signal distributor and relay also includes an amplifier.  
   
   
       3 . A milliwave-signal relay comprising a receiving antenna having a planar antenna formed on dielectric, transmitting antenna having a planar antenna formed on dielectric, and a blockage with said receiving and transmitting antennas mounted on opposite sides of said blockage and positioned opposite to each other.
