Abstract
A novel planar antenna is capable of feeding power to a plurality of radiation elements at a low loss and has a construction suitable for mass production. The antenna comprises a multilayer substrate formed by laminating at least two dielectric substrates and having at least an upper layer, an intermediate layer and a lower layer, upper conductive plate provided with a plurality of slots and laid in the upper layer, at least one strip line formed in the intermediate layer so as to correspond to the plurality of slots, and a lower conductive plate formed in the lower layer. At least two slots correspond to the strip line, the strip line has a feed point to which a center conductor 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.
