Stack type circularly polarized antenna structure

The invention discloses a stack type circularly polarized antenna structure, which comprises a first antenna, a second antenna and an adhesion component. The first antenna comprises a first base body, a first electrode layer, a first grounding layer and a first feed-in assembly, the first electrode layer and the first grounding layer are arranged on the two faces of the first base body correspondingly, and the first feed-in assembly penetrates through the first base body, is electrically connected with the first electrode layer and is not electrically connected with the first grounding layer. The second antenna comprises a second base body, a second electrode layer and a second feed-in assembly, the second electrode layer is arranged on one face of the second base body, and the second feed-in assembly penetrates through the second base body and the first base body, is electrically connected with the second electrode layer and is not electrically connected with the first grounding layer. The adhesion assembly
