PROBLEM TO BE SOLVED: To provide a receiving device that suitably receives a radio signal with high directivity.SOLUTION: A communication system 100 comprises: a reproducing device 110 for reproducing large capacity data such as high resolution moving image from a medium such as a Blu-ray Disc; a transmitting device 120 for transmitting the reproduced data from the reproducing device 120 by superposing it on a radio signal 121; a receiving device 130 for receiving the radio signal 121 from the transmitting device 120; and an outputting device 140 for outputting reproduced data such as displaying the received moving image on a screen. An antenna at the receiving device 130 side is configured and arranged so as to maintain an excellent reception characteristic even when arrangement and orientation relative to the front of an antenna of the transmitting device 120 side is varied more or less. |
