Patent attributes
The object of the present invention is to propose a re-radiating antenna system that efficiently radiates radio waves emitted from the antenna of a portable wireless device and efficiently receives incoming radio waves. To realize this object the re-radiating antenna system according to the present invention comprises coupling means for receiving radio waves radiated from the antenna of a portable wireless device, re-radiating means for re-radiating radio waves received by the coupling means and transmission means for transmitting radio waves received by the coupling means to the re-radiating means. The antenna of the portable wireless device and the coupling means are each formed of patch antennas, and these patch antennas are disposed to oppose each other.
