<p>A novel planar antenna is capable of feeding power to a plurality of radiation elements at low loss and has a construction suitable for mass production. The antenna comprises a multi-layer substrate formed by laminating at least two dielectric substrates (21, 22) and having at least an upper layer (23), an intermediate layer (24) and a lower layer (25), an upper conductive plate (26) provided with a plurality of slots (2) and laid in the upper layer (23), at least one strip line (3) formed in the intermediate layer (24) so as to correspond to the plurality of slots (2), and a lower conductive plate (8) formed in the lower layer (25). At least two slots (2) correspond to the strip line (3), the strip line (3) has a feed point to which a centre conductor (5) included in a high-frequency signal transmission line is connected, and a grounding point to which a grounding conductor included in the high-frequency signal transmission line is connected is formed on a second conductive surface. <IMAGE> <IMAGE></p> |
