Microwave antenna structure
 A suspended line feed type planar antenna has a substrate sandwiched between a top plate and a bottom plate, in which a number of protrusions are formed on the top plate and the bottom plate at a plurality of corresponding positions by deforming the top plate and the bottom plate by means of a press-process or press-treatment, so that the substrate is supported by the protrusions.
