Heterogeneous material integration antenna

A heterogeneous material integration antenna, comprising:

• a grounded conductive layer;
• a dielectric layer, spaced apart from the grounded conductive layer by a first distance and having a first dielectric constant;
• a plurality of dielectric pieces, each formed in the dielectric layer, wherein the plurality of dielectric pieces are adjacent to one another and arranged in a dielectric array, an outline of an outermost edge of the dielectric array forms a dielectric region having an area, adjacent ones of the plurality of dielectric pieces spaced apart from each other by a second distance, the plurality of dielectric pieces each have a second dielectric constant, and a magnitude of the second dielectric constant is higher than a magnitude of the first dielectric constant;
• and
• an antenna conductive structure, disposed between the grounded conductive layer and the dielectric array, wherein the antenna conductive structure is electrically connected to at least one signal source, the at least one signal source excites the antenna conductive structure to generate at least one resonant mode, and the at least one resonant mode covers communication frequency band;
• wherein the dielectric region is spaced apart from an outermost edge of the dielectric layer.
