  • Patent number: 11329386
    Abstract: The invention comprises a device for receiving electromagnetic signal and radiating the signal further. With that device the signal can be repeated on the other side of a barrier, for example a wall, which prevents the signal to propagate. The receiving section (1) of the device has been made as a planar aperture antenna, as well as the re-radiating section (2). The above-mentioned planar aperture antenna has been made so that between the antenna parts of conductive material (6) there is an opening (7) which opens in the propagation direction of the signal (4 and 5). Between the above-mentioned receiving section (1) and the re-radiating section (2) there is a signal transmission section (3) which has been implemented as two parallel conductors (8) with a gap (9). The transitions between the receiving section (1), the signal transmission section (3) and the re-radiating section (2) have been realized in stepless manner without separate connectors.
