ABSTRACT:
The present invention relates to a phase array antenna comprising a dielectric substrate (1) comprising a front and a back dielectric face (2, 3), a plurality of dipole means (4), each comprising a first and a second element (5, 6) for radiating and receiving electromagnetic signals, said first elements (5) being printed on said front face and pointing in a first direction and said second elements (6) being printed on said back face (3), and pointing in a second direction opposite to said first direction, metal strip means (7) for supplying signals to and from said dipole means (4), said metal strip means (7) comprising a first line (8) printed on said front face (2) and coupled to said first element (5) and a second line (9) printed on said back face (3) and coupled to said second element (6), and reflector means (10) spaced to and parallel with said back face (3) of said dielectric substrate (1), a low loss material (11) being located between said reflector means (10) and said back face (3), and having a dielectric constant less than 1.2, whereby said first and second lines (8, 9) respectively comprise a plurality of first and second line portions (13, 14), said first and second line portions (13, 14) respectively being connected to each other by T-junctions (15), whereby each of said first and second line portions (13, 14) is tapered between two adjacent T-junctions (15), so that the width of each line portion (13, 14) increases towards said first and second elements (5, 6), respectively, to provide an impedance transformation in the succeeding T-junction (15). The present invention relates to a low cost wide band planar printed antenna solution for microwave and mm-wave range. A particular solution for 60 GHz is introduced.
