| 摘要 |
The present invention relates to an antenna (1), comprising a dielectric substrate (2) comprising a front (3) and a back (4) dielectric face, at least one dipole element comprising a first (5) and a second (6) element for radiating and receiving electromagnetic signals, said first element (5) being printed on said front face (3) and said second element (6) being printed on said back face (4), said first and said second element having a spiral shape, respectively, both spirals being open, and metal feeding elements for supplying signals to and from said dipole element, said metal feeding elements comprising a first line (7) printed on said front face (3) and to said first element (5) coupled at a first feeding point and a second line (8) printed on said back (4) face and coupled to said second element (6) at a second feeding point, said first and said second feeding point overlapping each other. The present invention further relates to a phased array antenna comprising a plurality of proposed single antenna elements (1) with a feeding network based on tapered structures.
