Abstract

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.

Claims

1. A re-radiating antenna system comprising:

a coupling means for receiving radio waves radiated from the antenna of a portable wireless device;

a re-radiating means for re-radiating radio waves received by said coupling means; and

a transmission means for transmitting radio waves received by said coupling means to said re-radiating means,

wherein said antenna of said portable wireless device and said coupling means are each formed of a patch antenna, these patch antennas being disposed in opposition to each other,

wherein a loss in transference between said portable wireless device and said coupling means is less than 1 decibel (db).

2. The re-radiating antenna system according to claim 1, wherein said transmission means transmits said radio waves by electromagnetic coupling of said coupling means and said re-radiating means.

3. The re-radiating antenna system according to either of claims 1 or 2, including a portable wireless device holder.

4. The re-radiating antenna system according to either of claims 1 or 2, including a wearable antenna mounted on clothing, wherein said coupling means, said re-radiating means and said transmission means of said wearable antenna are comprised of flexible materials.
